General Area of Research
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.
