First brain experiments

Events

Piere Flourens

1820

Brain ablation

Gustav Frisch and Eduard Hitzig

1870

ESB Discover motor cortex

Karl Lashley

1920

Ablation to search for the location of learning and memory. Discovered not in one place but scattered.

Wilder Penfield

1940

Maps the cortex using ESB

Roger Sperry

1965

Split Brain experiments. Two cerebral hemispheres specialise in different tasks.
