Neuroscientists have identified more than 30 distinct cortical and sub-cortical areas in the primate brain that contribute to visual processing. However, we really only understand the specific contributions a small number of the areas make to visual perception. In my laboratory we use a combination of neurophysiological, psychophysical, and computational methods to study the contributions of occipital and parietal cortex to visual perception and action. We use nonlinear system identification techniques to analyze both single neuron responses in extrastriate cortex and psychophysical performance data from subjects performing attentionally demanding visual search tasks. These data are used to construct visual selectivity profiles for both single neurons and individual subjects. By using similar methods to study both single neurons and perception we can accurately estimate the contributions of single neurons to perception and action. The primary focus of this research is characterizing the effects of top-down modulatory signals on visual perception and to determine how the visual system influences the oculomotor system to guide eye movements during natural visual exploration of the world around us.
