Christopher J. Brandon, PhD
Dr. Brandon received his BS in biology from Northwestern University in 1969, and a PhD in biochemistry from the Albert Einstein College of Medicine in 1974. His postdoctoral research was carried out in the Laboratory of Functional Neuroanatomy at the National Institutes of Health, and in the Department of Cell Biology at Baylor Medical School.
From 1980 to 1983, he was an assistant professor in the departments of Anatomy and Ophthalmology at the Oregon Health Sciences University. He was part of the Chicago Medical School faculty in the Department of Cell Biology and Anatomy from 1984 to 2016.
The long-range goal of Dr. Brandon's research was an understanding of mechanisms of neural computation. Using the eye as a model for the brain, his work was concerned with determining how certain visual neurons distinguish the direction of motion of a visual stimulus, in both vertebrate and invertebrate visual systems.
In vertebrates, these directionally-sensitive neurons provide the brain with visually-derived information about the movement of the eye with respect to the real world; this information is then used in reflexes that control gaze. Similar neurons have been observed in the visual systems of crustaceans and insects.
The neuronal circuitry responsible for directional selectivity resides completely within the retina (in vertebrates) or the optic lobe (in invertebrates), and involves interactions among directional neurons and cholinergic and/or GABAergic interneurons. Dr. Brandon's research employed immunocytochemical methods and electron microscopy to identify the detailed connections among these cell types.
