2. Neuroanatomy

The lecture explores the importance of motion perception and the brain's mechanisms for processing it. It begins with a demo illustrating how difficult it is to discern emotion and lip-read with stop-motion. The discussion then transitions to the neuroanatomy of motion processing, covering the brainstem, cerebellum, limbic system, and cortex. Nancy Kanwisher explains the function of different brain regions, including the thalamus as a sensory relay station and the hippocampus's role in memory, referencing the case of patient H.M. The lecture also investigates visual area MT, presenting evidence from monkey and human studies, including direction-selective neurons and the akinetopsia patient.
