Question

what are the roles of V4, MT, inferior temporal cortex and posterior parietal cortex in visual processing

Answer 1

Role of V4 :

These neurons receives information from both V1 and V2 and transfer the received signals to the inferior temporal cortex. It generally receives information about the properties of an object like color, brightness and texture. It is also responsible for determining the shape, orientation, curvature, motion, and depth of an object.

Role of MT :

It plays a great role for the processing of visual information of a moving object. It helps in determining the speed and direction of a moving object.

Role of inferior temporal cortex :

The P - cells receives information about color and form of an object from the cone cells and the neurons present in the inferior temporal cortex precesses these informations received by the P - cells.

Role of posterior parietal cortex :

It is responsible for planned movements, spatial reasoning, and attention for visualizing an object.
