26th January 1891 - Wilder Penfield was born.

On 26th January 1891 — Wilder Penfield was born.

Penfield was a neurosurgeon who carried out surgical studies of epilepsy. Through the administration of local anesthetic, the surgeon removed part of the skull to expose brain tissue and, by the use of probes, the conscious patient described to the surgeon his/her feelings so that the surgeon could identify the location that evoked seizure activity. Then the surgeon would remove the brain tissue in this location to try to remove the epilepsy.

As a side effect of these operations, Penfield was able to identify various brain centers and to create maps of the sensory and motor cortices of the brain. He also discovered that electrical stimulation of portions of the cortex could evoke vivid experiences of events.

In 1954, Penfield published with Herbert Jasper one of the greatest classics in neurology, Epilepsy and the Functional Anatomy of the Human Brain.

Thankyou to Today in Psychology History for the date.
