Three-dimensional eye and head movements are recorded using the dual search coil technique during combined linear and angular accelerations of human subjects. The effects of head and orbital position on the axis of eye rotation is studied, as well as deviation from Listing's law in neurological disorders. The context in which a change in linear acceleration is interpreted centrally as due to either a tilt with respect to gravity or translation is investigated, as well as the postural consequences of this differential processing. Dwight Stambolian, M.D., Ph.D. Associate Professor, Department of Ophthalmology Peter Sterling, PhD. Professor, Department of Neuroscience Understanding the structure and function of neural circuits in the retina. Structure and changes in structure at different light levels are studied by intracellular dye injection combined with confocal and electron microscopy.
Function is studied by computer modelling of the circuit architecture.
Richard A. Stone, M.D. Professor, Department of Ophthalmology Glaucoma, ocular innervation and pharmacology, experimental myopia. I have constructed three-dimensional models of the binding domain based on homology with a cAMP binding domain from a bacterial protein. I am also interested in understanding the ion selectivity of the channel. John C. Trueswell, M.A., Ph.D. My two areas of research are language comprehension and visual perception. Within visual perception, I have focused on how the perceptual system uses visual properties of surfaces to organize a representation of the scene and to constrain ambiguity in seemingly unrelated visual domains, such as motion perception.
