Course Description
This course examines the neural bases of visual and auditory processing for perception and sensorimotor control, focusing on physiological and anatomical studies of the mammalian nervous system as well as behavioral studies of animals and humans. Visual pattern, color and depth perception, auditory responses and speech coding, and spatial localization are studied.
The first twelve lectures are devoted to the organization of the visual system and eye-movement control. Topics covered during those lectures are: the retina, the lateral geniculate nucleus and the visual cortex, the parallel channels of the visual system, the processing of color, motion, depth and form, and the neural control of visually guided eye movements. The twelve lectures that follow the midterm exam focus on audition. At the end of the semester, the last session will provide an overview of the auditory and visual systems.
