Cognition: perception, 3: perception/memory.
Two distinct pathways have evolved in primates for serving the kind of visual memory whereby visual stimuli are preserved in temporary memory traces so that the information is available for a few seconds after the stimulus is gone. These are a dorsal pathway for spatial memory and a ventral pathway...

These are a dorsal pathway for spatial memory and a ventral pathway for object memory. The implementation of functional magnetic resonance imaging (fMRI) to measure regional changes in blood oxygenation has facilitated the evaluation of these visual memory pathways in the human brain. The results of a human fMRI experiment that compared the visual memory task of remembering the location of a face presented on a screen with the task of remembering the identity of the face reveal sustained activity in the prefrontal cortex during the memory delay period of both tasks. It is speculated that the development of cortical regions in humans to serve language and human executive functions have pushed the dorsal and ventral pathways further apart in the human brain than in the nonhuman primate brain, more superiorly for spatial memory and more inferiorly for object memory. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: N holdings: @attributes: islocal: N |
