655-321 Visual Physiology and Perception

Optometry 655-221, 655-222; biochemistry 521-204 or equivalent. Exemption may be obtained with the approval of the Head of Department.

This subject provides students with a thorough understanding of processing of visual information by the visual pathways (retino-geniculate-striate system) and the physiology of other ocular components. The subject is presented in a problem-oriented approach and is therefore designed to develop students' skills in reading, analysing and debating scientific papers in the vision sciences. The topics to be studied include the neuro-anatomy of the visual pathways in the context of functional deficits; neuro-transmitters and synaptic circuits; regulation of visual sensitivity, including perception of motion; retinal and cortical electro-physiological responses; post-natal visual development; ocular growth and factors affecting refractive development of the eye; and corneal function and the effects on corneal function of metabolic stress.

A 2-hour written examination at the end of the semester (60%). Seminar participation and presentations (40%). A pass must be obtained for seminar participation.

Comprehensive reading material in the form of reference lists and reference material will be provided.
