Leslie Ungerleider is a Distinguished Senior Investigator and Director of the Laboratory of Brain and Cognition at the National Institutes of Mental Health. Ungerleider is known for introducing the concepts of the dorsal (where) and ventral (what) streams, two pathways of information processing in the brain that specialize in visuospatial processing and object recognition, respectively. Ungerleider received a B.A. from SUNY-Binghamton and a Ph.D. in experimental psychology from New York University, and she completed a postdoctoral fellowship with Karl Pribram at Stanford University, where she began her work on higher-order perceptual mechanisms in the cortex of primates. She then moved to the NIMH, where she has remained since, in 1975, initially joining Mortimer Mishkin in the Laboratory of Neuropsychology and establishing her own laboratory in 1995.
