Brenda Atkinson Milner (née Langford), CC, GOQ, FRSC, FRS, neuropsychologist (born 15 July 1918 in Manchester, England). Dr. Milner pioneered the field of neuropsychology, combining neurology and psychology. Most notably, she discovered that the part of the brain called the medial temporal lobe (which includes the hippocampus) is critical for the forming of long-term memories. Milner’s later work revealed that the learning of skills involving the combination of vision and movement is not part of the medial temporal lobe system. These discoveries proved that there are different forms of memory in different brain regions. Through her observation of patients, Milner changed forever our understanding of the brain’s learning and memory mechanisms.
