Affiliations Professor of the Graduate School, Division of Neurobiology, MCB Research Interests Optics and the eye; retinal and central processing of spatial visual information Behavioral measurements of sensory discrimination in humans often yield remarkably small values. At first glance, they may seem incompatible with the anatomical and physiological detection apparatus; for example, binaural time intervals …

Research Interests Clinical electrophysiology (ERG, EOG, VEP) of normal vision, and of inherited and acquired retinal disease; mechanisms of color vision in normal and color defective eyes; development of new techniques of clinical electrophysiology

Duties Professor of the Graduate School Research Interests Binocular vision; human development, ocular motility, strabismus, and amblyopia The central theme of my research activities is motor-sensory properties of binocular vision. Oculomotor studies are of accommodation, vergence, and yoked versional eye movements. Studies of accommodation investigate its stimulus (contrast increment thresholds and odd-error cues such as …

Duties Professor of the Graduate School Teaching Optometry 441A-C. Specialty Clinics

Research Interests High Resolution Neuroscience in Humans Single Cone Psychophysics We are using Austin Roorda’s adaptive optics scanning laser ophthalmoscope (AOSLO) for human psychophysics (for details go to Roorda’s information). The AOSLO has the capability of stimulating individual cones repeatedly, with the ability to go to the same cones over years. AOSLO’s unique capabilities enable …

Research Interests Clinical psychophysics and basic aspects of human color vision; binocular vision Basic studies of chromatic organization of human parafoveal retina. These psychophysical studies address the general issue of chromatic organization of sensitivity control at parafoveal locations as compared with the fovea. Studies of mechanisms of visual loss with aging. Vision changes with age …

Duties Senior Lecturer Emeritus Diplomate in Binocular Vision and Perception (AAO) Teaching Optometry 240. Diagnosis and Treatment of Sensory/Motor Anomalities Instructor-in-Charge Diagnosis and treatment of heterophoria, accommodative, vergence and oculomotor anomalies including sensory anomalies and amblyopia; rationale and methods for treatment with lenses, prism, occlusion, and vision training; design and implementation of treatment programs.

Duties Member of groups in Neuroscience, Bioengineering, and Biophysics; and the Helen Wills Neuroscience Institute Research Interests Central Visual Pathways: Systems and Computational Neuroscience Our laboratory is concerned with the neural organization of central visual pathways in the brain. We are interested in how visual information is encoded, transmitted and detected. We seek to determine …
