Visual Representation and Short-Term Memory in Inferotemporal Cortex
It is increasingly evident that the cortical processing and representation of sensory data of any modality extend well beyond the primary sensory cortex and occupy substantial parts of the associative cortex. According to electrophysiological and imaging studies, the temporal and spatial characteristics of the cortical representation of a discrete stimulus vary greatly depending on several factors, most notably its modality and its associations with past experience. In the primate, both the processing and the representation of a stimulus tend to follow certain anatomical gradients that conform to the patterns of connectivity originating in primary sensory areas and spreading through association cortex (Pandya and Yeterian, 1985). In the case of vision, those gradients extend into the inferotemporal (IT) cortex.
