DESCRIPTION:The way we perceive an object's color is determined both by it
 s surroundings and by our attentional state. In this talk I will describe 
 a series of neuroimaging experiments that we have performed to examine the
  way that color and contrast signals are represented in early human visual
  cortex. We show that V1 neurons are modulated by chromatic and achromatic
  contrast well beyond their classical receptive fields and that they appea
 r to be grouped into macroscopic domains that show specialization for eith
 er color discrimination or spatial feature discrimination but not both."\n
