The processing of visual information by the human brain is approached by psychophysical experiments, by the study of the primate visual cortex in a collaborative arrangement with the Neurobiology Laboratory at the Rockefeller University, and by models of neural circuits and brain mechanisms. Of particular interest are interactive and plastic changes associated with the response modifications that occur with attention, active perception and learning.
Current projects include the experimental study of perceptual learning in spatial visual tasks and new means of demonstrating the underlying synaptic changes in the involved brain circuits. Of continued interest are the geometrical, computational and perceptual problems associated with form vision, with stereoscopic viewing of three-dimensional configurations and with the interaction of stimuli transmitted to the brain through the right and left eyes.
