Representation of Movement

Motion sensitivity is a fundamental aspect of vision allowing the tracking, avoidance, and interception of objects, the extraction of depth information, and the calibration of proprioception and locomotion. Cortical motion sensitivity is a primary feature of the dorsal stream, with neurons in areas V1, V2, MT, and MST showing progressively greater sensitivity to movement and specializations for analyzing motion. This article focuses mainly on the neural representation of visual motion in primates, addressing how this representation changes along the interconnected hierarchy of brain regions that contain motion sensitive neurons and how this encoding ultimately affects perception and behavior.
