Functional magnetic resonance imaging (fMRI) has been used extensively to identify regions in the inferior temporal (IT) cortex that are selective for categories of visual stimuli. However, comparatively little is known about the neuronal responses relative to these fMRI-defined regions. Here, we compared in nonhuman primates the distribution and response(More)
Faces convey information about identity and emotional state, both of which are important for our social interactions. Models of face processing propose that changeable versus invariant aspects of a face, specifically facial expression/gaze direction versus facial identity, are coded by distinct neural pathways and yet neurophysiological data supporting this(More)
Optimal perceptual decisions require sensory signals to be combined with prior information about stimulus probability. Although several theories propose that probabilistic information about stimulus occurrence is encoded in sensory cortex, evidence from neuronal recordings has not yet fully supported this view. We recorded activity from single neurons in(More)
