Rapid face adaptation distributes representation in inferior-temporal cortex across time and neuronal dimensions

Abstract Neuronal networks of the brain adapt their information processing according to the history of stimuli. Whereas most studies have linked adaptation to repetition suppression, recurrent connections within a network and disinhibition due to adaptation predict more complex response patterns. Th...
