Brenda Milner

Proved the brain keeps two kinds of memory.

The neuropsychologist whose work with patient H.M. showed that remembering facts and remembering skills run on different systems.

He learned the task, but he had no idea he had ever done it before.
— Brenda Milner

Who they were

Brenda Milner met a man known publicly as H.M., who after surgery for epilepsy could no longer form a single new conscious memory. Each time they met, he greeted her as a stranger. But when she had him trace a star while watching his hand in a mirror — an awkward task — he got steadily better at it day after day, while insisting each morning he had never tried it before. His hands remembered what he could not. That result split memory in two: the declarative memory for facts and events that runs through the hippocampus, and the procedural memory for skills that does not. It reshaped the science of memory, and Milner was still publishing past her hundredth birthday.

Memory Systems

Brenda Milner's work with patient H.M. showed memory is not one faculty but several. Facts and events run through the hippocampus; skills and habits do not — which is why a man who could form no new memories still got better at a task he swore he had never tried.
