Dr. Kiviniemi’s recent focus has been on using an extremely high-speed MRI technique called MREG. This technique allows for the collection of an entire volume of data with a TR of just 100 milliseconds, using a stack-of-spirals approach. The reason he values this technique so much is that it enables him to examine various types of brain pulsations, including cardiac and respiratory pulsations, as well as what he refers to as glymphatic or CSF pulsations. In this episode, Dr. Kiviniemi explores how he has applied this technique in his research. He also discusses the history of our understanding of the glymphatic system, its potential functions, the many unknowns surrounding it, and the opportunities it presents for future research. Among other topics, he explains why using this high-speed technique might complement—or in some cases even be better than—slower approaches in certain ways. We hope you enjoy the conversation!

He's also the Director of the Cognitive Neuroscience of Schizophrenia Laboratory at BC Mental Health and Addictions Research Institute in Vancouver. Dr. Woodward received his Ph.D. in Experimental Neuropsychology at the University of Victoria in 1999, and performed his post-doc in the department of psychology at UBC. Since 2003 he's moved up from research scientist to professor - all at the University of British Columbia. He's been working at the interface of processing methods and well-crafted experimental designs to probe the networks that may be disrupted in schizophrenia and other disorders. He and his team developed almost two decades ago a unique and elegant method known as constrained principal component analysis ( or CPCA), which he has been applying successfully with many different tasks. He's also deeply interested in novel non-pharmaceutical interventions that help augment schizophrenia treatment - having developed a program called metacognitive training (MCT), which may allow those with schizophrenia to be able to step back and begin to assess their own beliefs. This was such a wide ranging conversation which delved into the nuts and bolts of CPCA as well as the potential future role that neuroimaging can play in better understanding and ultimately treating schizophrenia.

הפעל מאוחר יותר הפעל מאוחר יותר רשימות לייק אהבתיThis episode’s guest is arguably one of the most influential scientists in the human brain mapping community. Dr. Peter Fox, director of the Research Imaging Institute at the University of Texas Health, San Antonio. Early in his career he wrote the seminal paper that showed, using positron emission tomography , that brain-activation related increases in blood flow are accompanied by only small increases in oxidative metabolic - resulting in the blood locally increasing in oxygenation. This paper set the foundation for understanding all of Blood Oxygen Level Dependent Contrast used in fMRI today. The true purpose of activation-related flow increases is still an open question. The story of the events and details surrounding this are in his review article from the 2012 NeuroImage special issue. It's titled, simply "The coupling controversy." Dr. Fox was also among the first to promote data sharing and pooling with his brainmap database, and early on, established stereotactic coordinates and spatial normalization as a way to put data into a shareable space. He started the annual meeting that pre-dated the Organization for Human Brain Mapping, and also founded one of the major brain mapping journals today, titled: Human Brain Mapping. Peter had his formative undergraduate education at the extremely unique St. Johns college in Annapolis. He received his MD from Georgetown University, interned at Duke University, then carried out his residency and fellowship at Washington University where he worked closely with Dr. Mark Raichle, who was at the time pioneering PET scanning. In this discussion, we delve into his contributions in a wide range of topics, from neurovascular coupling to the challenge of spatial normalization - particularly at high resolution - to subject variability, to clinical applications and the ongoing evolution of scientific publishing.

הפעל מאוחר יותר הפעל מאוחר יותר רשימות לייק אהבתיIn this episode, our guest is Rotem Botvinik-Nezer, a postdoc at Dartmouth University, working with Dr. Tor Wager in his Cognitive and Affective Neuroscience Lab. In 2020, Dr. Botvinik-Nezer was first author of an influential paper published in Nature, titled Variability in the analysis of a single neuroimaging dataset by many teams, where the results were compared from 70 independent teams analyzing a single data set having 9 hypotheses. This paper made it clear that there are many points of variability in data analysis pipelines, and provided further incentives for sharing data and code to grow consensus and replicability. While the popular press suggested that this paper was yet another hit to fMRI, we discuss how even papers that critique the results of this seminal paper ultimately converge in agreement with the overall message of systematic transparency. Dr. Botvinik-Nezer also has a strong interest in how our brains influence our perception of pain, having just published a recent paper showing evidence that regions associated with painful stimuli remain active even when subjects experience less pain while having the belief that a placebo is effective. In this conversation, Peter and Rotem delve into all these topics and more, but spend the bulk of the discussion on the interplay between choices in analyses, such as determining a statistical threshold, and variability in results. We also discuss incentives for users to share data and code and possible ways to create a more solid scaffolding for best practices. Episode producers: Omer Faruk Gulban Xuqian Michelle Li…

For over a decade he has been showing us what further information and insight we may extract from brain imaging data - from EEG and MEG to fMRI. He is technically a statistical physicist, but in reality, he is a network neuroscientist and data modeler who is constantly pushing the envelope. In this podcast he discusses some recent papers that go into how we might be able to improve the impact and relevance of new findings and models through careful benchmarking and well considered experimental design. He talks about his desire to move from correlation to causation in functional connectivity studies, he discusses granger causality, as well as moving from pairwise correlation to multivariate correlation. Furthermore, he delves into the limits of hemodynamics - limits that may be pushed back to a degree, as suggested by his compelling work showing that hemodynamic response function, which varies over space, may be estimated on a voxel-wise basis using resting state data alone. His work in estimating and mapping the Excitation/Inhibition ratio in the brain by using gamma frequency coherence as a signature was also discussed. This has potentially profound clinical and research applications. Lastly, his collaborative work with the European Human Brain Project towards the creation of the useful website, called ebrains ( https://www.ebrains.eu ), was discussed, which serves as a repository and tool for exploring shared data and code, as well as providing a user-friendly encapsulation of the project's collective effort. It is an all-around fun, eye-opening discussion featuring an outstanding scientist who is not only deep in the trenches of network modelling, but also a strong proponent of open science and constant engagement across disciplines.

Dr. Chen is the go-to statistics guru for the fMRI community at the NIH and a well-respected scientist worldwide. He is a staff scientist in the group that developed the AFNI software package. As an applied mathematician, Dr. Chen has written a series of insightful papers in the past seven years, bucking the status quo in fMRI processing - essentially saying that we are throwing away too much valuable information by thresholding our data, relying on overly simple and rigid models of the hemodynamic response, not mapping effect sizes, and using center of mass measures to describe clusters of activation. He backs it all up with a rigorous approach characterized by all good statisticians. He is a master in the art of casting a wide net to capture useful data without taking in artifact and noise, finding that sweet spot in data reduction to balance utility with sensitivity. In this episode, we hear all about Dr. Chen’s perspectives through these papers, which are so important yet not widely known or embraced by the field. We hope you enjoy it!

Dr. Wells received his Ph.D. in MRI in the Department of Medical Physics and Bioengineering at at University College London in 2010, and since he began his scientific career, he's been working at the interface of MRI methodology and neurophysiology - focusing on understanding the Cerebral Spinal Fluid dynamics and how they may relate to the Glymphatic system. He and his colleagues have been among the leaders in using MRI to image and characterize the glymphatic system as well as the brain - cerebrospinal fluid barrier. The glymphatic system is hypothesized to be the paravascular mechanism by which CSF is washed through brain tissue - typically during sleep - clearing out metabolic waste. It is an incompletely understood yet potentially profoundly important system where its dysfunction may be at the root of disorders that include Alzheimer's disease.

Dr. Mesulam is Chief of Behavioral Neurology and the Ruth Dunbar Davee Professor of Neuroscience at Northwestern University Feinberg School of Medicine, and Professor of Behavioral Neurology at the Weinberg College of Arts and Sciences. Dr. Mesulam received his MD from Harvard Medical School in 1972, and in 1976 completed residencies at Boston City Hospital and Beth Israel Deaconess Medical Center in Boston. After a 1 year postdoc at Harvard University he began his tenure in Chicago at Northwestern. Dr. Mesulam's work has been both prodigious and impactful over the years, as his almost 1000 papers have been cited over 140 thousand times. He has written the seminal book, Principles of Behavioral and Cognitive Neurology, and has produced many landmark papers - a few of which we'll discuss in the podcast. One paper that we consider a masterpiece was published in Brain in 1998 and titled From Sensation to Cognition. This can be considered as a required reading for everyone in the field of brain mapping as it lays out so concisely and eloquently, a breathtaking perspective of the structure and functional organization of the human brain. Dr. Mesulam's research is extremely broad and diverse, having impacted such areas as neural networks and functional imaging, Dementia, Alzheimer's Disease, Primary Progressive Aphasia (PPA), Cholinergic Pathways, Acetylcholinesterase Studies, Cognitive Psychology, Neurology, and Neuropsychiatry. He also developed, early in his career, a neuronal marker, Tetramethyl benzidine, that profoundly impacted research in this area. In this inspiring conversation, Peter and Marsel discuss his early career and what was important for his success, delve into research culture and the value of opportunistic research, and the value of having the freedom and resources to try many things and rapidly change directions that follow interesting leads. They also discuss some of the exciting early days of Neuroimaging and OHBM. Lastly, we go into some of his current research on Primary Progressive Aphasia (PPA) and the study of temporal pole disease as a window to temporal pole functional significance.

In 2019, she started as an assistant professor in the Department of Psychology at the University of Chicago and is a member of the Chicago Neuroscience Institute. She has been pioneering the use of connectome-based predictive modeling to capture individual differences in the ability to sustain attention. Attention is fundamental to just about everything that we experience and do and how we navigate the world. It varies over time and each person has different abilities to maintain it. Monica has developed and used extensively a task known as gradCPT, an easy at first but hard to sustain, continuous attention task that allows moment to moment assessment of sustained attention. She has found two networks that characterize high attention vs lower attention, and these have been powerful for characterizing individuals ability to sustain attention. It's also been useful for characterizing differences in such attention-related skills such as reading comprehension. She's been delving further into both fMRI methodology and the nuances of attention ever since.

This powerful approach in fMRI is known as "deep sampling." His findings include insights into unique individual connectivity patterns, the whole brain use of a novel parcellation approach using boundary maps, and most recently, discovery of effector-specific regions in motor cortex - a finding which is likely to replace in textbooks the classic Penfield maps of the homunculus.

She went on to a do a post-doc at NIH in Dr. Alan Koretsky's lab and in 2004 joined the department of Biomedical Engineering at Emory University as a faculty member. She is now a full professor at Emory University and also closely affiliated with Georgia Tech. Since around 2008 she has been uncovering new spatial and temporal patterns in resting state fMRI. She was the first to identify spatial propagation of wave-like behavior in the resting state time series and in 2011 coined the term quasi-periodic patterns (QPP) to describe whole brain networks that dominate much of the resting state signal. Recently, she and others have described three such patterns that account for most of the variance. Here we not only talk about her career but also delve into how these quasi-periodic patterns mesh with the current landscape of diverse features of resting state fMRI that continue to be found. She has shown that these patterns may have a central driver and may relate to such things as vasomotion, global signal, arousal state, and attention. In general, there is much more information from basic neurophysiology to cognition that remains to be derived from resting state fMRI, and Shella is among those leading the effort.

His main interest and research focus lies in the development and improvement of methods to analyze brain stimulation sites to study network interactions of neuromodulation in the human brain. He is also the host of a podcast focusing on brain stimulation. In the interview with Dr Horn we explore how the impact of deep brain stimulation on the connectome can be studied, and how it can be used to improve patients lives. “In contrast to many other neuroimaging domains, there is a more or less direct translation [..] to clinical practice”, says Dr Horn, and explains how for example networks that have been identified via DBS can later be targeted with noninvasive stimulation methods such as multifocal transcranial direct current stimulation (tDCS), for example to improve patients’ conditions in movement disorders such as Parkinson's disease. Among many other things, Dr Horn also lets us in on an informally ongoing challenge at Harvard University whether structural or functional measures provide better predictions for DBS outcomes. He explains why his lab has gradually shifted away from using patient specific connectivity data to precise normative connectomes for studying which brain networks should optimally be modulated for maximal effects. In his keynote at OHBM 2023 , Dr Horn will give us a tour through his findings from years of work studying the effects of deep brain stimulation on the connectome across different disorders, ranging across neurological, neuropsychiatric and psychiatric diseases.

Prior to UCSB, she was an instructor at Harvard Medical School and at the Department of Medicine/Division of Women’s Health at Brigham & Women’s Hospital. In this episode we discuss the pioneering work of Dr. Jacobs and her group in leveraging brain imaging, computation, and endocrine approaches to deepen our understanding of the influence of sex hormones on the central nervous system across spatial and temporal scales. She discusses her group’s work using structural and functional neuroimaging methods to explore how the brain changes in response to endogenous hormonal changes, such as across the menstrual cycle, during menopause, or across pregnancy, as well as to exogenous hormones via oral hormonal contraceptives. Through the Ann S. Bowers Women’s Health Initiative, Dr. Jacobs and her group are working towards creating a population-level brain imaging dataset to advance our understanding of women’s brain health across the lifespan. Dr. Jacobs also shared her journey into neuroscience research, her thoughts on how science can inform public policy, and talked about her groups’ efforts to improve girls’ representation in STEM by partnering with K-12 groups. This work was featured in the book STEMinists: The Lifework of 12 Women Scientists and Engineers . At OHBM 2023, Dr. Jacobs will highlight the power of sex steroid hormones and the role that they play in shaping the brain over multiple timescales, drawing attention to some of the reasons why it has taken the field so long to focus on women’s brain health.

Along with clinical researchers around the world, they have been writing a massive white paper for the OHBM Best Practices Committee on the presurgical mapping of language function. They were also both co-authors on a clear and comprehensive 2022 paper published in the British Journal of Neurosurgery, titled: “Functional MRI applications for intra-axial brain tumors: uses and nuances in surgical practice” Here we have an in-depth discussion of the state of the art of fMRI as it’s used in the context of Neurosurgery. While fMRI is becoming a more commonly used tool for helping inform surgeons of brain tissue to be avoided during surgery, standards and best practices are still being worked out as the technique itself has so many stages including acquisition, brain activation paradigm design, processing, and finally interpretation. Natalie and Andreas are not only trained in neuroimaging, but very much in the weeds of daily surgical practice, so have extremely useful insights on all aspects of how fMRI can be and should be used for pre-surgical mapping. Dr. Bartsch is currently with Radiologie Bramber, and affiliated with the University of Heidelberg. He’s an MD/PhD Radiologist and Neuroradiologist who studied at Charite Hospital at the University of Berlin, Tufts University in Boston, as well as at the University of Oxford. Dr. Voets is an Associate Professor at the Nuffield Department of Clinical Neuroscience at the University of Oxford and a Special Advisor in Neuroimaging at Genesis Cancer Care.

She also serves as co-director of the Imaging Core for UC Davis Health's Alzheimer’s Disease Center, an NIH-funded Alzheimer’s research center. Dr. Fan is an imaging physicist and translational scientist. She develops novel magnetic resonance imaging (MRI) and positron emission tomography (PET) methods to study brain physiology in cerebrovascular disease and vascular dementia. She has translated new imaging technologies to patient studies in acute stroke, Moyamoya disease and intracranial stenosis. She received her Bachelor’s degree from Stanford, then her Ph.D. from the department of Electrical Engineering and Computer Science at MIT. She returned to Stanford for her post-doctoral training, and, recently moved to UC Davis to start up her own lab. Dr. Fan is one of only a handful of researchers who are wielding MRI to non-invasively extract, with ever more effectiveness, useful quantitative information about brain physiology that is also clinically relevant. This includes quantitative blood flow, volume, and oxygenation as well as cerebral metabolic rate and oxygen extraction fraction with a goal to help guide treatment and therapy for stroke, vascular dementia, and other neurovascular disorders. This is such an important area to work in - as MRI is so sensitive to so many physiologic variables with such a broad parameter space. Even at about 40 years old, MRI has untapped potential and clinical efficacy - which Audrey is working to utilize. This conversation gives a great perspective of the unique challenges and opportunities of this exciting subfield of MRI. ~ Episode producers : Omer Faruk Gulban Alfie Wearn ~ Brain Art Artist: Omer Faruk Gulban Title: OHBM22 Brain Art ~ Please send any feedback, guest suggestions, or ideas to ohbm.comcom@gmail.com…

הפעל מאוחר יותר הפעל מאוחר יותר רשימות לייק אהבתיIn this discussion, we cover her work on characterizing the variability of coherence as it relates to aging and how this coherence is increased by providing subject with ketones - an alternate source of energy to glucose. We then go into her work in modeling brain circuits and determining where the circuitry is altered across trajectories of disorders. In this context, we briefly discuss her work characterizing the effects on amygdala activation by different composition of inhaled perspiration - either that produced in a fear state vs that produced through exercise. Lastly, we discuss her lab’s work on neuroblox - a simulation program for testing circuit models of the brain and how it may open up the diagnostic value of brain imaging data. Guest: Lily Mujica-Parodi, Ph.D. is Director of the Laboratory for Computational Neurodiagnostics (LCNeuro) at Stony Brook University. LCNeuro's research focuses on the application of control systems engineering and dynamical systems to human neuroimaging time series (fMRI, MEG, EEG, NIRS, ECOG), with neurodiagnostic applications to neurological and psychiatric disorders. One of LCNeuro’s primary goals is to identify key points of failure in the regulation of neural control circuits which, depending upon how they break, lead to signs and symptoms that cluster as distinct psychiatric diagnoses. As a test case for this approach, her lab is working to understand how the prefrontal-limbic circuit “computes” potential threat in the face of incomplete sensory data, across a clinical spectrum that ranges from pathological fear (generalized anxiety disorder, phobia, post-traumatic stress disorder, paranoid schizophrenia) to recklessness. A second direction at LCNeuro considers fMRI connectivity as the solution to an optimization problem imposed, in part, by metabolic constraints at the mitochondrial scale. Her group uses biomimetic modeling to predict trajectories, based on biological “rules” of energy optimization, which are then validated against data. Experimentally, they expand and contract neurons’ access to energy while observing consequent self-organization and re-organization of networks. The hope is that this work will have important implications for understanding brain aging; specifically, the epidemiologically observed impact of insulin resistance on cognitive decline.…

Jeff Binder , M.D. is a professor and Vice-Chair for Research in the Department of Neurology at the Medical College of Wisconsin. In 1980, he received his BA in Music. In 1986, received is M.D. from the University of Nebraska Medical Center in Omaha. After further clinical and research training at University of Nebraska Medical Center, Northwestern University, and the Neurological Institute of New York a Presbyterian Hospital, he started at MCW in 1992 where he also began his fMRI research. Jeff's research focuses on neural systems underlying human language processing and concept representation, speech perception, reading, and aphasia. Much of this work is based on fMRI measurements in healthy people, combined with psycholinguistic and psychophysical measurements of behavior. His clinical practice focuses on patients with aphasia, and he studies the pathological correlates of specific language deficits in these patients using voxel-based lesion-symptom mapping and fMRI. He has also worked extensively on applications of fMRI for presurgical mapping, including development and validation of fMRI language lateralization methods and prediction of language and verbal memory outcomes. In the episode, we first trace his origin story - from a degree in music to receiving his M.D., then to his early work at MCW and the early days of fMRI. We go on to discuss some of the highlights of his work over his career, including his recent work putting forward the idea of the predominance of experiential-based concept representation in the brain, and that the hubs of this representation are within the default mode network. We also discuss a bit of his early work on characterising and mapping the default mode network, as well as his current work on Aphasic patients. The discussion finishes up with his thoughts on clinical applications of fMRI and how this may be pushed further. This episode was produced by Jeff Mentch and Stephania Assimopoulos.

הפעל מאוחר יותר הפעל מאוחר יותר רשימות לייק אהבתיThis week on #Neurosalience, we discuss one very cool and very useful fMRI acquisition strategy called Multi-echo EPI. While it’s been around for over 20 years, only a fraction of papers reporting fMRI results have used it. It can help quite a bit towards increasing sensitivity, mitigating signal dropout and motion artifacts, and stabilizing the time series to allow for tracking of very slow changes. Recent papers have come out showing that it significantly helps increase sensitivity and mitigate artifacts. In fact, several prominent leaders in the field are embracing it as they are convinced it's essential for increasing the reproducibility and ultimately, the clinical utility of fMRI. In this podcast we cover what Multi-echo EPI can and can’t do. We also discuss the options in pulse sequence parameters, what vendors offer, and fMRI processing, and available processing packages set up to work with multi-echo data. Guests: Charles Lynch, Ph.D. is a postdoctoral associate in Neuroscience and Psychiatry at Weill Cornell Medicine in New York who received his Ph.D. in 2018 from Georgetown University in Washington DC and has written several impactful papers convincingly describing the benefits of multi-echo EPI for fMRI. Prantik Kundu, Ph.D. is a pioneer in multi-echo EPI processing, having developed the powerful approach called ME-ICA to process multi-echo EPI data. In 2014, Prantik received his Ph.D. from the University of Cambridge. He was a student of both Ed Bullmore and myself, working in the NIH-Cambridge graduate program. He was assistant professor at Mount Sinai in New York before moving to be a lead scientist at Hyperfine (the company that came out with the ultra-low field portable scanner). Recently, he has started in the position of Chief Technology Officer at Ceretype Neuromedicine, a company based in Boston that is pioneering precision neuropsychiatry - towards increasing the clinical relevance of functional brain imaging.

הפעל מאוחר יותר הפעל מאוחר יותר רשימות לייק אהבתיFunctional MRI is a profoundly successful and powerful technique that so many of us use. It’s still developing and adding to our insight about the human brain. While MRI was developed in the late 1970’s and early 80’s, it would be another decade before it was realized that MRI could be used to detect and map, non-invasively, human brain activation. My guests today, Ken Kwong, Bob Turner, and Ravi Menon were the first who showed this capability. Ken’s successful experiment in early May of 1991 was arguably the first. Ravi, who was the key player in the Minnesota group, had produced solid fMRI results by the summer of 1991, and I had my first successful experiment in Sept of 1991. Bob Turner was a key player in his physiologic manipulation experiments in Cats. He collaborated with Ken, and also showed results of his own at 4T shortly after as well. We were all there at the Society for Magnetic Resonance Imaging Meeting in San Francisco in August of 1991 when Tom Brady (who headed MGH NMR Center at the time), first showed in his plenary lecture, the crude but stunning jaw dropping brain activation movies. The moment I saw that, I knew what I wanted to do for the rest of my career. We have them all here to reflect on those heady days, what led up to their findings, and the bright future of fMRI. Guests: Ken Kwong has been conducting MRI research at the Mass General Hospital since the late 80’s when he pioneered diffusion imaging, as well as perfusion imaging approaches. He’s currently associate professor at the MGH Martinos Center. Robert Turner trained with inventor of Echo Planar Imaging, Peter Mansfield, among others, and while working at the NIH, performed those first critical experiments, demonstrating BOLD contrast as well as obtaining some of the first results in humans at 4T using his home built gradient coil. One of Bob’s major contributions to the field was his early work in gradient coil design - which remains fundamental to what we do. From 2006 to 2014 he was the Director of the Department of Neurophysics at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig and is currently retired and living in Cambridge, England. Ravi Menon was a post doc at Minnesota and a driving force in the effort to produce functional images using a highly challenging non-EPI approach at 4T. He has been a steady contributor to fMRI methods ever since and is currently a Robarts Scientist and Canada Research Chair in Functional Magnetic Resonance Imaging, Co-Scientific Director of BrainsCAN which is Canada First Research Excellence Fund, Scientific Director, Centre for Functional and Metabolic Mapping, and Professor of Medical Biophysics, Medical Imaging & Psychiatry at The University of Western Ontario…

He moved back to Italy, to teh University of Padua, in 2016. Prof. Corbetta has pioneered experiments on the neural mechanisms of human attention using Positron Emission Tomography (PET). He has discovered two brain networks dedicated to attention control, the dorsal and ventral attention networks, and developed a brain model of attention. His clinical work has focused on the physiological correlates of focal injury. He has developed a pathogenetic model of the syndrome of hemispatial neglect. He is currently developing novel methods for studying the functional organization of the brain using functional connectivity MRI, magneto-encephalography (MEG), and electro-corticography (EcoG). He is also working on the effects of focal injuries on the network organization of brain systems with an eye to neuromodulation. He is known for the high level of rigor and deep insight of his research, and has over 16 papers with over 1000 citations.

Denis is the founding director of NeuroSpin in Orsay, France and spends time in Japan as a guest professor at the University of Kyoto and National Institutes of Physical Sciences in Okazaki. Denis Le Bihan has achieved international recognition for his truly fundamental contributions to the development of diffusion MRI, diffusion tensor imaging (DTI), and the concept of IVIM to image perfusion. It is the b in his name from which the ubiquitous b-factor in diffusion comes from. He has more recently demonstrated the ability to image brain activation-related diffusion coefficient changes. In this podcast, we discuss the intellectual history of Denis’ career. He produced the first diffusion-weighted images, helped establish diffusion tensor imaging, and advanced the concept of imaging perfusion as having an “apparent diffusion coefficient” (ADC) and order of magnitude higher than water diffusion. He has also demonstrated that water diffusion, when imaged with very high b-values, decreases with brain activation. Cell swelling increases the surface area of cells where low diffusion coefficient water resides, thus lowering overall diffusion coefficient. This last result is still debated but generally gaining acceptance with each new paper demonstrating the effect. He also spends some time in the episode talking about his foray into modeling brain function, tapping into inspiration from Einstein and relativity. Overall, it was a fun and inspiring conversation!…

He thinks that more model free approaches and paradigm free methods are ultimately limited. The discussion gets technical as well as intense at times; while Jack and Peter agreed most of the time, there were some nuanced differences of opinion - mostly when it came to discussing alternative methods for probing fMRI data. Overall, we think it was a fun and hopefully a useful discussion! What comes through is Jack’s passion for what he does. Given that they only barely got started with Peter’s questions, Peter invited him back for another chat - see S2 Episode 6!…

הפעל מאוחר יותר הפעל מאוחר יותר רשימות לייק אהבתיPeter talks to Bob Cox, Ph.D., Gang Chen, Ph.D. and Paul Taylor, Ph.D. about AFNI. AFNI is a major processing package used by brain mapping groups all over the world. It is nearly as old as fMRI itself, and has been steadily growing in functionality. Here we discuss the history of how it all started as well as a few of the challenges of fMRI processing that have arisen over the years. Importantly, time is spent discussing more of the philosophy of data analysis and visualization. A key tenet that AFNI has always encouraged is the ability to drill down and look directly at the data. This ability to flexibly and efficiently visualize the data at all processing steps not only guards against problematic data and hidden artifacts but is also a catalyst for new analysis ideas. We discuss a bit of the future of analysis and the bottleneck for clinical implementation. Guests: Bob Cox, Ph.D. is the creator of AFNI and still leads a team, the Scientific and Statistical Core, at the NIH which helps users and continues to develop AFNI. Bob received his Ph.D in Applied Mathematics from Caltech, and after several industry positions and a short stint at Indiana University and Purdue University, he moved to the Medical College of Wisconsin where he began to create AFNI. He moved to the NIH in 2001 where his work accelerated as he was allowed to grow a team of programmers to further advance AFNI. Gang Chen, Ph.D. joined the AFNI team at the NIH in 2003. He is a staff scientist and the chief statistician for things fMRI and related. He received his PhD. from the University of Arizona, Tucson and has been recently pushing our understanding of variability in large N datasets. Paul Taylor, Ph.D. joined the AFNI team in 2015. He received his D. Phil in Astrophysics from Oxford University, and performed post docs at the University of Cape Town and with Bharat Biswal in New Jersey. He has been leading the effort to incorporate diffusion imaging and tractography into AFNI For more info on the Neurosalience podcast and the guests, visit: ohbmbrainmappingblog.com Keywords: #brain #imaging #software #data #fMRI #research #clinical…

הפעל מאוחר יותר הפעל מאוחר יותר רשימות לייק אהבתיThis week, Peter talks to Dr. Melanie Boly, a neurologist and neuroscientist who has worked for more than fifteen years in the field of altered states of consciousness such as vegetative state, sleep and anesthesia. In this wide ranging discussion, Peter and Melanie address everything related to her work on consciousness. They start with some of her early work on resting state as a modulator for detecting subtle stimuli and then get into a discussion on a working definition of consciousness and her work on understanding the neural correlates of consciousness. Melanie is a proponent of the idea that many, if not all, of the fundamental physical correlates of consciousness reside in the posterior part of the brain. Peter and Melanie also discuss Integrated Information Theory (IIT): how it helps us begin to understand consciousness. Last they consider her studies of sleep and how dreaming is not limited to REM sleep. This interesting discussion straddles theoretical work and practical clinical applications of brain imaging.
