MACAQUE STRIATE CORTEX: PATTERN, MOVEMENT AND COLOUR PROCESSING

Abstract

Abstract Simple cells in the primate visual cortex provide a form of generalized, pre‐cognitive mapping of visual scenes. One point in space is represented by several orientation‐specific cells capable of signalling both standing contrast and contrast changes in the scene. The arrangement of simple receptive fields (with a few antagonistic subregions) suggest analysis of scenes both in terms of symmetrical and antisym‐metrical spatial components (i.e. lines and edges) and spatial‐frequency contents. There is no evidence that this analysis is carried out within fixed areas (or patches) since a diversity of receptive field sizes was observed. A chromatic content is probably analysed by a diffe..
