Cross-Collaborative Exploration of Psilocybin's Effects ft. Odilia Lu, Dr. Robert Malenka & Dr. Boris Heifets 58:14

לפני 15 ימים58:14

58:14

The final episode of Season 4 of Psychedelic Brain Science discusses a recent preprint that gets at the heart of reproducibility in science. Dr. Jaster is joined by Berkeley PhD candidate Odilia Lu, Stanford researcher and professor Dr. Robert Malenka, and anesthesiologist and Stanford researcher Dr. Boris Heifets, all representing the laboratories involved in the Psychedelic Bay Area Animal Neuroscience Consortium; Psy-BAANC. Five laboratories performed the same experiments at Stanford, Berkeley and UCSF to test the acute and persistent effects of 2 mg/kg psilocybin on various behaviors that psychedelics have been proposed to affect in mouse models. Many of these methods have been featured in publications that have received a lot of media attention, but can be difficult to replicate. This body of work titled “A multi-institutional investigation of psilocybin’s effects on mouse behavior” can be found on BioRxiv here: https://www.biorxiv.org/content/10.1101/2025.04.08.647810v1…

Science Under Threat! ft. Dr. Hilary Marusak & Dr. Christine Rabinak 59:07

59:07

In this special episode of Psychedelic Brain Science , Dr. Alaina Jaster is joined by Dr. Hilary Marusak, host of BrainSTEM and Principle Investigator in the THINK lab at Wayne State University. They are also joined by Dr. Christine Rabinak, a world-leading PTSD researcher, who brings a unique perspective on the impact of recent federal funding cuts—not just on scientific innovation, but also on patients whose lives depend on this research. The conversation centers on the Trump administration’s executive actions affecting NIH indirect costs and broader federal science funding freezes. These cuts threaten groundbreaking research, training the next generation of scientists, and the economic and public health benefits of biomedical innovation. Beyond the numbers, they also affect real people—patients with PTSD, cancer, and other life-threatening conditions who rely on scientific progress for hope and treatment. Scientists across the country are facing uncertainty, and the lack of clear information has created widespread concern. But there are ways to take action. In this episode, we highlight concrete steps researchers, advocates, and the public can take to push back against these harmful policies and fight for the future of science. 🔗 Topics Covered: How recent NIH funding cuts and freezes impact research, jobs, and innovation The ripple effects on early-career scientists and the next generation of researchers The role of science in shaping policy—and how policy shapes science Firsthand perspectives from both researchers and patients affected by these decisions Actionable steps for advocacy and protecting scientific funding 📢 Take Action: Contact your representatives via phone or email: https://www.usa.gov/elected-officials/ Make 5 calls in 5 minutes to advocate for NIH and NSF funding: https://5calls.org/issue/nih-nsf-funding-cuts/ Check out templates for emailing and a fact sheet specific to DEIA in health and drug policy here: https://ssdp.org/blog/action-alert-support-funding-for-scientific-research/ Sign petitions and stay informed through professional societies: https://www.sfn.org/Advocacy/Advocacy-Network/Advocacy-Action-Center/Available-Actions?fbclid=IwY2xjawIV8gtleHRuA2FlbQIxMAABHcoVtD4ypMm9S_YXTzJ-iORHELm4xuZwa5c8TaO6xT7ZgcGdJIso5bU6jA_aem_pRj4tTcv1XuHnCiQtkwfwQ#/29 Join activist groups and find more resources: Indivisible – Fighting against the constitutional crisis https://indivisible.org/ The People’s Union – Economic boycotts and protest organizing https://jointhepeoplesunion.com/ Stand Up for Science – Grassroots science advocacy https://www.standupforscience2025.org/STAND-UP-FOR-SCIENCE-2025-1965a8bd7a44806a8182dc6b75b80da2 🧠 Special thanks to the BrainSTEM production team for editing this recording: Amanpreet Bhogal, Manmeet Bhogal, and Gabby Maramag.…

Special Episode: Charting a Path Forward ft. Dr. Gill Bedi & Dr. Neşe Devenot 42:37

לפני 13 weeks42:37

42:37

This special episode includes presentations from a recent workshop, where Dr. Alaina Jaster, Dr. Neşe Devenot of Johns Hopkins and Dr. Gill Bedi of University of Melbourne presented their expertise and perspectives on how the psychedelic research field can move forward from the recent FDA rejection of MDMA-AT. Dr. Jaster's presentation sets the tone by going over recent events, followed by how researchers can be involved in promoting evidence-based regulatory and policy decisions. Dr. Devenot's presentation focused on what it means to be a psychedelic bioethicist and how the recent events have conflated constructive criticism with attacks, followed by a call to be better about having these discussions. Dr. Bedi's presentation discussed how scientists studying MDMA and other psychedelics can better their study design and use methodology that is evidence-based and thorough. These taken together, provided the framework for how to move forward in the field and prompted a discussion by members in the crowd (of which was not recorded to protect those participating).
