Today ' s Google Doodle Honors Neurosurgeon Wilder Penfield

Quoted fromKN Smith ofForbes:Today ' s Google Doodle celebrates the 127th birthday of Canadian neurosurgeon Wilder Penfield, who developed a groundbreaking epilepsy treatment called the Montreal Procedure.In the 1930s, while working as a neurosurgeon at the Montreal Neurological Institute at McGill University, Penfield had a patient who reported smelling burned toast just before her seizures. He realized that he could use that hallucinatory scent to pinpoint the part of the brain that was seizing - and put a stop to it.With the patient wide awake, but under local anesthetic, he used electrodes to stimulate parts of her exposed brain, asking her what she felt, saw, heard, or smelled each time. When she declared, " I smell burned toast! " Penfield determined that he must have found the center of her epilepsy. It worked; he removed a small piece of brain tissue from the spot, and the woman never had a seizure again. Penfield and his colleagues published a paper on the method in 1951, and since then it has helped bring relief to many epilepsy patients.Of course, there are many different kinds of epilepsy, and the Montreal Procedure doesn ' t work on all of them, but it made a significant difference for a large number of people. And Penfield performed the procedure more times than any other neurosurgeon working at the time. In the process, he assembled a detailed map of where sensory and motor functions happen in the brain, and which areas of the brain receive input from, or send ...
