Brenda Milner (born 1918)
Milner is best known for her work with "Patient H.M.," a man who lost the ability to form new memories after undergoing brain surgery for epilepsy. Through repeated studies in the 1950s, Milner found that Patient H.M. could learn new tasks, even if he had no memory of doing it. This led to the discovery that there are multiple types of memory systems in the brain, according to the Canadian Association for Neuroscience. Milner's work played a major role in the scientific understanding of the functions of different areas of the brain, such as the role of the hippocampus and frontal lobes in memory and how the two brain hemispheres interact.
Her work continues to this day. At age 103, Milner is still a professor in the Department of Neurology and Neurosurgery at McGill University in Montreal, according to the Montreal Gazette.https://www.livescience.com/amazing-women-in-math-and-science.html
