In the following feature we give you an electric probe and an exposed brain. All you need to do is shock and observe. NOTE: The brain's motor cortex—the subject of this feature—controls body ...

By doing so, he discovered that weak electric shocks, when applied to areas at the back of the brain, caused the patients' eyes to move. Wilder Penfield, a pioneering brain surgeon, mapped the ...

It can feel like an electric shock that travels from the head down ... In MS, the immune system attacks and destroys myelin in the brain and spinal cord, slowing down the signal that travels ...

He and his team genetically engineer brain cells associated with memory in mice to respond to light. Then they create a bad memory—a mild electric shock—and watch the activated cells light up.
