Neurosalience #S6E3 with Kendrick Kay - Philosophy, deep sampling, and the advancing tide of AI

“What does it actually mean to understand the brain?”Dr. Kendrick Kay is a computational neuroscientist and neuroimaging expert at the University of Minnesota’s Center for Magnetic Resonance Research, where he is an Associate Professor in the Department of Radiology. With training spanning philosophy and neuroscience, from a bachelor’s degree in philosophy at Harvard University to a PhD in neuroscience from UC Berkeley, Dr. Kay’s work bridges deep theoretical questions with cutting-edge neuroimaging methods.In this conversation, Peter Bandettini and Kendrick Kay explore the evolving landscape of neuroscience at the intersection of fMRI, philosophy, and artificial intelligence. They reflect on the limits of current neuroimaging methodologies, what fMRI can and cannot tell us about brain mechanisms, and why creativity and human judgment remain central to scientific progress. The discussion also dives into Dr. Kay’s landmark contributions to fMRI decoding and the Natural Scenes Dataset, a high-resolution resource that has become foundational for computational neuroscience and neuro AI research.Along the way, they examine deep sampling in neuroimaging, individual variability in brain data, and the challenges of separating neural signals from hemodynamic effects. Framed by broader questions about understanding benchmarking progress, and the growing role of LLM’s in neuroscience, this wide-ranging conversation offers a thoughtful look at where the field has been and where it may be headed.We hope you enjoy this episode!Chapters:00:00 - Introduction to Kendrick Kay and His Work04:51 - Philosophy’s Influence on Neuroscience17:17 - How Far Will fMRI Take Us?23:27 - Understanding Attention in Neuroscience30:00 - Science as a Process34:17 - The Role of Large Language Models (LLMs) in Scientific Progress38:29 - Why Humans Should Stay in the Equation40:30 - Creativity vs. AI in Scientific Research54:48 - Dr. Kay’s Natural Scenes Dataset (NSD)01:00:27 - Deep Sampling: Considerations and Implications01:08:00 - Accounting for biological variation in Brain Scans: Differences and Similarities01:13:00 - Separating Hemodynamic Effects from Neural Effects01:16:00 - Areas of Hope and Progress in the field01:21:00 - How Should We Benchmark Progress?01:22:59 - Advice for Aspiring ScientistsWorks mentioned:54:48 -  https://www.nature.com/articles/s41593-021-00962-x54:50 - https://www.sciencedirect.com/science/article/pii/S0166223624001838?via%3DihubEpisode producers:Xuqian Michelle Li, Naga Thovinakere

"AI is really bad at perspective taking…"Dr. Charlotte Grosse Wiesmann is a cognitive neuroscientist exploring how the human social brain takes shape in early life. She is a Professor at the University of Technology Nuremberg and directs the Research Group on Social Brain Development at the Max Planck Institute in Leipzig. Her research blends developmental psychology, brain imaging, and computational modeling to uncover how infants begin to infer other people’s beliefs, intentions and mental states. In this conversation, Dr. Wiesmann unpacks how children’s brains develop the capacity for social understanding and theory of mind. Drawing on developmental psychology and neuroimaging, she reveals how the brain transforms as children first succeed on false-belief tasks, a fleeting yet powerful window into the emergence of the social mind. Within this context, the conversation explores white matter maturation, environmental influences, and brain plasticity, offering fresh insights into how studying infant development can inform the future of AI. Join the conversation to discover how early brain development is reshaping our understanding of our social minds.We hope you enjoy this episode!Chapters:00:00 - A Journey from Physics to Neuroscience14:25 - Neural Bases of Early Childhood Theory of Mind21:58 - False Belief Task and Theory of Mind25:11 - Attention Schema for Consciousness27:14 - Primary Areas Involved in Theory of Mind31:24 - Impact of Neuro Deficits on Social Cognition33:57 - Role of Environment and Timing on Social Cognition37:11 - Implicit and Explicit Mechanisms of Social Development45:02 - Social Cognition Across Species47:37 - Connecting Neural Code to Social Cognition49:56 - Temporal Progression in Theory of Mind Tasks54:54 - Future Research Directions in Understanding Social Cognition01:00:08 - Infant Learning Inspires AI Development01:04:50 - Advice for Aspiring ScientistsWorks mentioned:14:31 -  White matter maturation is associated with the emergence of Theory of Mind in early childhood37:20 -  Two systems for thinking about others’ thoughts in the developing brain49:50 -  Timing matters: disentangling the neurocognitive sequence of mentalizingEpisode producers:Xuqian Michelle Li, Karthik Sama

Early career researchers give their perspectives on being an academic today. With Arshiya  Sangchooli, Natasha L. Taylor, Ashlea Segal, Stefano Moia, Jiajia Yang, and Peter Bandettini Episode ProducersOmer Faruk GulbanXuqian Michelle Li

Peter Bandettini interviews Dr. Rosanna Olsen, a senior scientist at the Rotman Research Institute and the University of Toronto. She is pioneering what we know about human memory and its associated structures, primarily focusing on the hippocampus, the role it plays, and how it changes with age and neurological diseases. Her work has shed light on how the hippocampus facilitates the flexible binding and comparison of new and existing information. She has also shown how visual exploration reveals memory processes, and has uncovered promising early dementia biomarkers based on measures of visual exploration and hippocampus. Dr. Olsen is also a leader in education. She is co-lead of the Research Training Center in Toronto, disseminating essential knowledge and skills to younger scientists, and is chair-elect of the OHBM education committee. She is also the leader of a consortium organized to reach a consensus on hippocampus segmentation. Lastly she's an avid and accomplished runner, having run the Boston Marathon, as well as many others.We hope you enjoy the conversation! Episode ProducersOmer Faruk GulbanXuqian Michelle Li
