Wilder was considered at the time “the greatest living Canadian” as he was responsible for pioneering advances in the mapping of brain surgery techniques to treat epilepsy .
Penfield’s contributions to modern neuroscience raised Canada’s global state of health care, science and discovery, while its innovations created better lives for people suffering from epilepsy.
In one of his investigations, he carried out his idea of performing surgery on patients who were awake using a sensitive electrical probe to observe the effect of brain stimulation on the body. He considered that it was a new approach and never before raised in the exercise of neurology, so he did not hesitate to apply it to patients with more severe epilepsy.
The innovation of the Canadian neurosurgeon was to use electrical impulses in several areas of the brain and, based on the testimony of the conscious patient, to know which areas were affected and reduce the risks during surgery.
This practice, known as Montreal Procedure, also allowed compiling maps of the sensory and motor cortex of the brain, which are those that present the connections of the cortex to the various limbs and organs of the body and that continue to be used today. Wilder Penfield discovered them.
He was someone who wanted to make the world a better place through medicine, so Google honors him with a doodle.
