PSYCH 1XX3 Lecture Notes - Lecture 8: Extrastriate Cortex, Visual Cortex, Cortical Column
Document Summary
The layout of the visual scene is preserved in the visual cortex. Cluster of cells in the region of the cortex right beside this region are doing the same analysis for the neighboring part of the visual scene: an important benefit of this parallel processing strategy is speed. The processing of visual input in the primary visual cortex involves specific cells responding to relatively specific features from a small portion of the visual field. But for the visual scene to make any sense, this information has to be combined to form a meaningful whole. This combination begins in the extrastriate cortex, also known as visual association cortex, which surrounds the primary visual cortex. It is in the extrastriate cortex where the information begins to be segregated into two streams according to the type of information that is processed. , where all the bits of feature information come together.
