Dr. Roozbeh Kiani
Professor, Neural Science and Psychology, New York University
Summary: Flexible behavior requires flexible decision-making. We adapt seamlessly to changing environments鈥攁djusting biases, altering decision rules, and inferring hidden task contexts鈥攐ften without explicit cues. In this talk, I will outline a framework that formalizes different levels of this flexibility and show how these adjustments are implemented in neural codes across the frontoparietal cortex. I will highlight three forms of decision flexibility: (1) Bias adjustments, driven by asymmetric rewards, shift neural activity along the decision variable axis; (2) Rule changes, such as varying sensory weights in a multi-feature discrimination task, produce rotational changes in the population geometry, supporting rapid changes in decision policy; and (3) Hierarchical inference, where animals infer hidden contexts to adapt to task structure, is reflected in the emergence of latent variables represented in distributed subspaces.

Theory to practice: Decoding Multimodal Recovery Signals to Optimize DBS for Depression
Summary: Deep Brain Stimulation is an experimental treatment for intractable depression. Next-generation technologies now provide real-time tracking of neural activity from the implanted device and combined with advances in neuroimaging, computer vision and machine learning strategies, enable neural and behavioral monitoring and during ongoing DBS. Such studies work to link first-person experiences to changes in brain state and naturalistic behaviors, and a mechanistic approach towards a comprehensive understanding of illness, recovery and resilience.

In Search of Mental Models
Mental models allow us to organize information about the world into an abstract structure that facilitates decision-making and further learning. How are such models represented in the brain? I will discuss work in collaboration with Beth Buffalo, and our progress in evaluating the structure of mental models from neural recordings of nonhuman primates performing schema-based tasks.
Dr. Annegret Falkner
December 11, 2025
Annegret Falkner is an assistant professor of neuroscience at the Princeton Neuroscience Institute. She earned her PhD from Columbia University, and her research focuses on neural circuits for social decision-making. Her lab is interested in how social experience and internal state shapes sensory perception and social motivation in order to influence behavioral choice. Specifically, it focuses on understanding the interplay between circuit nodes in the brain鈥檚 鈥渟ocial decision-making network,鈥� areas in the hypothalamus, amygdala, and midbrain that process social-sensory information and drive social behaviors. Her lab uses genetic tools in mice in tandem with in vivo physiology and optical recording strategies to probe how activity in these networks changes as a function of experience and neuromodulatory and hormonal influences.

David Robbe is an INSERM research director and leads the 鈥楥ortico-Basal Ganglia Circuits and Behaviour鈥� team at the Institute of Neurobiology of the Mediterranean (INMED, Marseille). After completing his PhD in Montpellier 听on the molecular determinants of synaptic 听plasticity in the ventral striatum, David Robbe did his postdoc in Gyorgy Buzsaki鈥檚 lab where is studied study the relationship between neuronal population dynamics in the hippocampus and spatial memory. David Robbe then led a research team in Barcelona as part of the Ramon-y-Cajal program before joining INMED in 2012.
Tom Griffiths
April 24, 2025
Tom Griffiths is the Henry R. Luce Professor of Information Technology, Consciousness and Culture in the Departments of Psychology and Computer Science at Princeton University. His research explores connections between human and machine learning, using ideas from statistics and artificial intelligence to understand how people solve the challenging computational problems they encounter in everyday life. He has made contributions to the development of Bayesian models of cognition, probabilistic machine learning, nonparametric Bayesian statistics, and models of cultural evolution, and his recent work has demonstrated how methods from cognitive science can shed light on modern artificial intelligence systems. Tom completed his PhD in Psychology at Stanford University in 2005, and taught at Brown University and the University of California, Berkeley before moving to Princeton. He has received awards for his research from organizations ranging from the American Psychological Association to the National Academy of Sciences and is a co-author of the book Algorithms to Live By, introducing ideas from computer science and cognitive science to a general audience.

Talk Title: Large-scale pretraining on neural data allows for transfer across individuals, tasks and species
As neuroscience datasets grow in size and complexity, integrating diverse data sources to achieve a comprehensive understanding of brain function presents both an opportunity and a challenge. In this talk, I will introduce our approach to developing a multi-source foundation model for neuroscience, utilizing large-scale pretraining on neural data from various tasks, brain regions, and species. This model is designed to enable seamless transfer learning across individuals, tasks, and species, thereby enhancing data efficiency and advancing the capabilities of neural decoding technologies. By integrating diverse datasets, our aim is to uncover the common neural functions that underlie a wide range of tasks and brain regions, providing a deeper understanding of brain function and informing future brain-machine interface applications.
