1 Endocannabinoid contributions to the perception of socially relevant, affective touch in humans 9:13
New drugs that target the endocannabinoid system are being proposed for disorders that are usually characterized by the dysregulation of social processing, like social anxiety disorder and autism spectrum disorder. Researchers have been trying to understand the mechanisms for how these drugs work. Leah Mayo is assistant professor at the University of Calgary, and she’s one of the authors of a new study in the journal Neuropsychopharmacology in which they examined two aspects of the system. One is the endocannabinoid system itself. And then there’s another aspect of social processing called the C tactile system.

1 Sex differences in sensitivity to dopamine receptor manipulations of risk-based decision making in rats 9:46
The scientific literature has shown that females demonstrate more aversion to risk-taking than males. Studies have also demonstrated that the basal lateral amygdala, or BLA, is a critical hub for processing risk and reward information. And yet further research has shown that activity in the amygdala differs between males and females, and that the expression of particular dopamine receptors called D2 receptors are greater in females than in males. The authors hypothesized that one mediating mechanism that leads to greater risk aversion in females is differential activity of dopamine in the basal lateral amygdala. Caitlin Orsini is an assistant professor in the departments of psychology and neurology at UT Austin. Hosted on Acast. See acast.com/privacy for more information.…
1 Biomarker development for menstrual Cycle affective change: the need for greater temporal, mechanistic, and phenotypic specificity. 9:39
The menstrual cycle is known to affect things like mood and changes in pain. But there can also be symptoms that have a serious impact on a person’s function, ability to work, ability to maintain friendships and romantic relationships. This is a rare condition known as premenstrual dysphoric disorder. But it’s not the only psychiatric condition that can worsen with changes in the menstrual cycle. For instance, nearly 60 percent of menstruating patients with depression can experience cyclical worsening similar to PMDD. Conditions such as these are generally referred to as menstrual cycle affective change. Menstrual cycle affective change is more common in those with chronic psychiatric disorders. The authors are interested in reframing the conversation around menstrual cycle affective change to be something that is a more fundamental process that we can study across disorders, across categories, and identify biomarkers that might help us predict who's going to have those symptoms in more complex ways than we might be able to do with categories. This paper represents how can we take this dimensional way of thinking about menstrual cycle affective change and talk about the specific ways that we can be precise in looking at the time the time characteristics of that, the specific mechanisms, et cetera. Tory Eisenlohr-Moul is an associate professor of psychiatry at the University of Illinois at Chicago in the department of psychiatry, and she’s one of the authors. Jordan Barone is an MD/PhD candidate at the University of Illinois at Chicago, and she’s another author. Hosted on Acast. See acast.com/privacy for more information.…
1 Genome-wide association studies of coffee intake in UK/US participants of European ancestry uncover cohort-specific genetic associations 9:39
Researchers are interested in understanding the biology of why some people are more likely to overconsume substances. Some substances are difficult to study—people might not admit to illegal substance abuse or to how much alcohol they drink. But Americans are more likely to accurately recall and share how much coffee they drink—which is related to how much caffeine they consume. And so a team of researchers paired up with the company 23 and Me to try to understand genetic differences among a large set of people, to try to tease out any genetic similarities that could be correlated with coffee consumption. Sandra Sanchez-Roige is an associate professor in the department of psychiatry at the University of California San Diego, and she’s one of the study’s authors. Abraham Palmer is a professor and vice chair of basic research in the department of psychiatry at UC San Diego, and he’s another of the study’s authors.

1 C-reactive protein moderates associations between racial discrimination and ventromedial prefrontal cortex activation during attention to threat in Black American women 9:56
Scientists have been amassing an increasing amount of evidence about the impact of racial discrimination and racial trauma, including how it can have an impact on brain regions involved with threat vigilance and emotional regulation. At the same time, there’s evidence that increased engagement in those areas has been linked to increased risk of mental health problems like depression, and they also suspect it could be a vulnerability for brain health issues such as dementia and Alzheimer’s disease. Negar Fani is an associate professor in the department of psychiatry and behavioral sciences at Emory University School of Medicine, and she worked with Aziz Elbasheir, a PhD candidate at Emory University in the neuroscience program, on the study. They knew that C-reactive proteins, or CRPs, are a marker of immune activation in the blood. Read their full study here: https://www.nature.com/articles/s41386-023-01737-7 Hosted on Acast.

1 Ghrelin decreases sensitivity to negative feedback and increases prediction-error related caudate activity in humans, a randomized controlled trial 9:06
There’s a hormone called ghrelin that’s secreted in the stomach, and when someone is hungry it contributes to that feeling of hunger and the need to search for food. But neurological studies have suggested that ghrelin might also play a role in compulsivity and impulsivity, and it might be related to substance use disorders. Rebecca Boeme is an assistant professor at Linkoping University in Sweden. She and her colleagues decided to use human subjects to investigate how ghrelin affects reinforcement learning, basically how ghrelin influences decision making when subjects receive positive and negative feedback —and also how it might actually be affecting the brain.

Dr. Nicole Petersen is an assistant professor in the department of psychiatry and behavioral sciences at UCLA. Her commentary is a new paper in the journal Neuropsychopharmacology, called “Spotlighting SHAPERS: sex hormones associated with psychological and endocrine roles.” Dr. Petersen starts the paper describing an unnamed signaling molecule that can affect the physical structure of the brain and that seems to be related to a wide number of psychological and neurological conditions. Then she reveals that this is estradiol. The point she makes in the paper is that estrogen isn’t the only neuroactive substance that affects the brain in ways that we just don’t understand.

1 Comparable roles for serotonin in rats and humans for computations underlying flexible decision-making 9:33
Serotonin is a critical chemical when it comes to a number of psychiatric conditions, such as OCD, where it seems to play a particular role in cognitive flexibility. That is, serotonin levels are related to the fact that someone is perseverating on intrusive thoughts or compulsions and isn’t able to be as flexible as otherwise would be necessary. Trevor Robbins, professor of cognitive neuroscience at the University of Cambridge, is one of the authors of a recent study titled Comparable roles for serotonin in rats and humans for computations underlying flexible decision-making , and he says such cognitive flexibility also plays a role in depression and schizophrenia .

1 Integrating public health and translational basic science to address challenges of xylazine adulteration of fentanyl 9:58
The drug naloxone, otherwise known as Narcan, is a critical tool in reversing fentanyl overdoses and reducing mortality. But now fentanyl is appearing on the streets adulterated with a drug called xylazine. Justin Strickland, assistant professor at Johns Hopkins University School of Medicine, and Cassandra Gipson-Reichardt, associate professor in the department of pharmacology nutritional sciences at the University of Kentucky, are the coauthors of a new paper in the journal Neuropsychopharmacology about the importance of integrating public health and translational science to address the challenges of xylazine adulteration of fentanyl.

Sanjay Mathew is a professor and vice chair for research at Baylor College of Medicine and director of the Mood and Anxiety Disorders Program. He’s one of the two authors of a recent review paper in the journal Neuropsychopharmacology, “The why, when, where, how, and so what of so-called rapidly acting antidepressants.” With his colleague Alan Schatzberg, professor of psychiatry and behavioral sciences and director of the Mood Disorders Center at Stanford University, they explore both the drugs that have been studied as rapidly-acting anti-depressants to date, and they also review the challenges and opportunities in how such research is conducted. They say that a version of ketamine has changed the field. Read the full study here : https://www.nature.com/articles/s41386-023-01647-8 Hosted on Acast. See acast.com/privacy for more information.…
In-person treatment for substance use disorders is an incredibly important tool, but there’s a high failure rate — more than 50 percent of people who enter drop out within the first month. There hasn’t been a highly accurate method of identifying who might leave and who might succeed, and knowing this could help centers allocate resources to give the right type of assistance to the right people at the right time. One tool available is called the Addiction Severity Index, which is used to help identify the severity of the addiction and thus customize treatment, but it wasn’t developed to gauge whether a patient might drop out entirely. So a team of researchers decided to mine something known as a digital phenotype. Dr. Brenda Curtis is a clinical researcher at the National Institute on Drug Abuse Intramural Research Program, and she’s one of the paper’s authors.

Antisocial personality disorder, or ASPD, is a difficult disorder to study. There have been studies on psychopathic individuals, and on youth with psychopathic traits, but most studies on ASPD to date have been on incarcerated adults. A team of researchers at Heidelberg University wanted to study individuals who are not incarcerated and see what these findings could elucidate about the brains, in particular the amygdalas, of individuals with ASPD. Haang Jeung-Maarse is a medical doctor at Bielfeld University in Germany and is one of the authors of the paper in the journal Neuropsychopharmacology, on the effects of oxytocin on amygdala reactivity to angry faces in males and females with antisocial personality disorder.

It’s clear there are diversity issues in science, both in terms of who does or doesn’t receive research grants, as well as who is or isn’t represented at the highest levels of scientific research. When Caleb Weinreb and Daphne Sun began their PhD program at Harvard University Medical School in systems biology, they took this on as an issue. They learned from others in their department, and they eventually created a course on the topic for incoming first year PhD students. As they worked on improving their course over the years, they saw that in science there was a focus on narrowing racial gaps by correcting for implicit bias. For example, there had been a well-known study in which resumes with stereotypically African-American names weren’t considered as seriously as those with stereotypically white names. But the two PhD students realized that efforts to overcome such implicit bias weren’t moving the needle. They recently published a perspective paper in the journal Neuropsychopharmacology called “To dismantle structural racism in science, scientists need to learn how it works.” Caleb Weinreb is now a post-doc in the neuroscience department at Harvard Medical School.

Psychedelic drugs have received attention recently for their potential use as treatments for psychiatric disorders. Single, high doses of LSD have shown promise for treating depressive disorders. But there’s another way in which people have been using LSD, and it’s what’s known as micro-dosing, taking LSD at below noticeable levels, where it doesn’t seem to have a psychedelic impact—but users say it does in fact have an impact on their overall sense of well-being. This is just what Harriet de Wit, University of Chicago professor in the department of psychiatry and behavioral neuroscience, wanted to study. Dr. de Wit partnered with James Glazer, a postdoc in psychiatry at Northwestern University.

After a traumatic event, women are more likely to be diagnosed with post-traumatic stress disorder, or PTSD. Research has been conducted on what might be causing this higher rate of diagnoses; for instance, perhaps women had more cumulative trauma in their lives than the men in question. But scientists say that even taking prior childhood trauma into account, women are still diagnosed at a higher rate than men. Alyssa Roeckner is a neuroscience PhD candidate at Emory University, she’s in the lab of Dr. Jennifer Stevens, assistant professor in the department of Psychiatry and Behavioral Sciences at Emory University. They are two of the authors of a recent study in NPP titled “Sex-dependent risk factors for PTSD: a prospective structural MRI study.” Read the full study here: Sex-dependent risk factors for PTSD: a prospective structural MRI study | Neuropsychopharmacology (nature.com) Hosted on Acast.
