DESCRIPTION:Prof. Leon Y. Deouell\, Hebrew University of Jerusalem\, Isra
 el.\nThe world is mostly stable\, yet what we know about the neural basis 
 of visual perception is limited to responses to change and onset responses
 . To start filling this gap we recorded intracranial electrocorticographic
  activity from patients presented with visual stimuli of variable duration
 s to address the neural basis of visual sustained perception. Sustained co
 rtical activity tracking the duration of the stimulus (broadband gamma\; >
 30 Hz)\, was prominent in early visual cortex and decreased gradually alon
 g the ventral stream. In category selective areas on the inferior temporal
  cortex\, activity in posterior electrodes tracked the stimulus duration w
 hile in anterior sites it did not. The results show that analog informatio
 n about stimulus duration in the ventral stream follows a posterior-anteri
 or gradient\, and suggest functional differentiation within category-selec
 tive regions based on temporal response properties. The results highlight 
 the fact that full understanding of perception goes beyond onset responses
 .
