PSYB51H3 Chapter Notes - Chapter 4: Extrastriate Cortex, Inferior Temporal Gyrus, Temporal Lobe
Document Summary
What and where pathways: extrastriate cortex: the region of cortex bordering the primary visual cortex and containing multiple areas in visual processing, these areas are named v2, v3, and so on. Visual areas in this pathway are important for processing information relating to location of objects in space and the actions required to interact with them (moving hands, eyes). This pathway is sometimes called the where pathway: the other pathway heads down into the temporal lobe (what pathway). This pathway is the locus for explicit acts of object recognition. It cortex maintains close connections with parts of the brain involved in memory formation (hippocampus) important because it cells need to learn their receptive field properties: logothetis demonstrated that cells in it cortex have plasticity. Feed forward process: process that carries out a computation (e. g. object recognition) one neural step after another, without need for feedback from a later stage to an earlier stage.
