Born in Fitchburg, Massachusetts, Mishkin graduated from Dartmouth College in 1946, and took a 1949 M.A. and 1951 Ph.D from McGill University under Donald O. Hebb. His Ph.D thesis was partly directed by surgeon and theorist Karl H. Pribram.
In 2010 Mishkin won the National Medal of Science for his five decades of work on the mechanisms of cognition and memory, and the discovery that the brain processes memories in two separate processes: cognitive memory dealing with events and fresh information, and behavioral memory related to skills and habits.
As of 2016 Mishkin is Chief of the Section on Cognitive Neuroscience, Laboratory of Neuropsychology, National Institute of Mental Health, chartered to explore neurobiological mechanisms of perception and memory.
