Quick facts
Brenda Milner helped found cognitive neuroscience by showing that memory is not one faculty: after bilateral medial temporal surgery, patient H.M. lost new episodic memory while retaining skills, language and much of his past.
Her career at the Montreal Neurological Institute spanned decades of careful testing, frontal-lobe work and mentorship. The H.M. story is also an ethics story — consent, anonymity and the limits of what surgery can promise.
Educational history of neuroscience — not medical advice. Patient identities and clinical details are discussed at the level of published science.
