Which area of the extra striate cortex is involved in the perception of motion?

The perception of motion is primarily processed in visual area 5, also known as V5 or MT (middle temporal area). This region is responsibly specialized for detecting and interpreting movement in the visual field. Neurons in V5 are highly sensitive to the direction and speed of motion, making it integral to our ability to perceive dynamic changes in our environment.

In contrast, other areas mentioned, such as V2, V4, and V1, have different roles in visual processing. V1, for example, is the primary visual cortex and is involved in basic visual processing such as edges and orientations. V2 serves as a secondary processing area that helps integrate and interpret visual information but is not specialized for motion. V4 primarily deals with color and form recognition. Therefore, while all these areas contribute to visual perception, V5 is unique in its focus on analyzing motion, making it the correct choice for this question.
