Cognitive Maps in the Prefrontal Cortex
The prefrontal cortex (PFC) is critical for our ability to rapidly and flexibly adapt our behavior in new environments based on our previous experience. Despite its importance, the neural substrates a...

🚨New pre-print!🚨
Can we truly independently read and write neuronal activity at the same time using all-optical techniques? Here we show that even two-photon imaging over large fields of view with low dwell time per cell can bias neural dynamics!
Read on for some potential fixes: (1/5)

🚨We believe this is a major step forward in how we study hippocampus function in healthy humans.
Using novel behavioral tasks, fMRI, RL & RNN modeling, and transcranial ultrasound stimulation (TUS), we demonstrate the causal role of hippocampus in relational structure learning.

Our new paper out now in Science explores how neural activity in the lateral entorhinal cortex (LEC) *drifts* over time - and *jumps* at key boundaries - to help organize events in memory.

Happy to share the latest version of our work on compositional maps in hippocampus with Jo Warren, @jcrwhittington.bsky.social, @behrenstimb.bsky.social. We propose hippocampus constructs maps from cortical building blocks in replay – now with empirical support! www.nature.com/articles/s41... 1/9
Constructing future behavior in the hippocampal formation through composition and replay - Nature Neuroscience
A model of compositional state spaces in the hippocampus shows latent learning and rapid generalization. Bakermans et al. show that this model predicts the emergence of place responses in replay.
