72. Nico Schuck: Replay, cognitive maps, and multivariate decoding with fMRI

BJKS Podcast

Nico Schuck is Professor and head of the research group 'Mechanisms of learning and change' at the University of Hamburg, where his research focuses on the neuroscience of learning, memory, and cognitive maps. In this conversation, we discuss his work on cognitive maps and replay in Orbitofrontal Cortex and Hippocampus, decoding even brief events with fMRI, and much more.
BJKS Podcast is a podcast about neuroscience, psychology, and anything vaguely related, hosted by Benjamin James Kuper-Smith.
