Description: Charles Schroeder, Director of the Laboratory for Cognitive Neuroscience and Neuroimaging at The Nathan S. Kline Institute for Psychiatric Research and Professor of Psychiatry at Columbia University, is a neuroscientist interested in investigating the neural mechanisms of sensory and cognitive processes using methods that allow one to relate the functioning of single neurons and groups of neurons to that of the brain as a whole. Dr. Schroeder’s primary research method is to use brain electrical field potentials and their derivatives, in combination with action potentials, to study brain processing in awake non-human primates. Actual signals are collected from within the brain using multi-electrode arrays, and processed with 96 channel amplifier systems. Dr. Schroeder’s research staff is continually developing and refining this approach to increase our resolution of the way the brain interprets basic properties of sensory stimuli, and higher order properties such as an object's biological significance. Of particular interest at this point is the interaction of the stimulus-evoked response with ongoing oscillatory activity at each point in the system.
