The psychophysics and physiology of cognitive processes in the monkey.

Current Research

We study the psychophysics and physiology of cognitive processes in the monkey, using single unit recording, iontophoresis, and careful behavioral measurements. Current projects include elucidation of the cortical representation of oculomotor proprioception, using saccadic adaptation to understand the coordinate system of neurons in the lateral intraparietal area (LIP), the role of prestriate cortex in visual search, and the role of inhibition in the response of parietal neurons. Recent discoveries in the laboratory include the demonstration of a predictive relationship of parietal activity to both saccadic reaction time and visual attention; the demonstration that the lateral parietal area acts as a linear summing junction for at least three independent signals: a saccadic signal, and undifferentiated visual signal, and a cognitive signal, and the proprioceptive representation of eye position in monkey area 3a of primary somatosensory cortex.
