Sharpened visual memory representations are reflected in inferotemporal cortex
Humans and other primates can robustly report whether they’ve seen specific images before, even when those images are extremely similar to ones they’ve previously seen. Multiple lines of evidence sugg...

A landmark Computational Neuroscience book for our times, from basic principles to whole-cortex modelling of cognition, NeuroAI and Computational Psychiatry. This is one of Xiao-Jing's major achievements. Years of dedicated work from a master of the field.
As our community increasingly shifts toward embracing the complexity of the brain, this new book by Xiao-Jing Wang will be an essential go-to.
He is among a small, prescient group that embraced important ideas before the rest of us. Here he unpacks them. 1/2
