PSYB51H3 Chapter Notes - Chapter 4: Principles Of Grouping, Illusory Contours, Extrastriate Cortex
Document Summary
Extrastriate cortex: the region of cortex bordering the primary visual cortex and containing multiple areas involved in visual processing: v2 and v3, so on in monkey brain. From extrastriate regions of occipital lobe, visual information moves along two main pathways. One path up the parietal lobe: important for processing information relating to location of objects in space and action required to interact with them, where pathway, important role in deployment of attention. Second path down into temporal lobe: what pathway, appears to be in locus for act of object recognition, receptive fields bigger moving into temporal lobe. Kl ver and bucy: lesioned sections of temporal lobe in monkeys, monkeys behaved as though they could see but didn"t know what they were seeing, seen in some human stroke victims. Lesion: in reference to neurophysiology, 1. (n) a region of damaged brain. 2. (v) to destroy a section of the brain.
