PSYC 144 Lecture Notes - Lecture 5: Cerebral Hemisphere, Grey Matter, Semantic Dementia
Document Summary
O from there, info goes along ventral stream to temporal lobe (what pathway), or along dorsal stream to parietal lobe (where/how pathway) the what and where pathways experiments in monkeys. What: bilateral lesion of temporal lobe leads to a behavioral deficit in task that requires discrimination of objects (choose new object, the one that was not presented in earlier trial); they had no problem with where task. Where: bilateral lesion of parietal lobe leads to a behavioral deficit in a task that requires the discrimination of location (choose the food-well that is closer to. Landmark ); they had no problem with what task. Dorsal stream is also a how pathway- involved in processing of both location and action. Affects previous experiences as well as newly experienced faces. Representation of semantic memory in the brain notes visual stimulus info goes to primary visual cortex in occipital lobe (anterograde and retrograde components)
