A practical method of mapping the minute electrical impulses of the human brain has been achieved with computers, Sidney Goldring, MD, associate professor of neurosurgery at Washington University in St. Louis reported early in May. "We are now able to interpret minute electrical signals recorded from the surface of the human brain with data obtained with sophisticated bioelectric amplifiers and one of the most recently designed digital computers," Goldring said.
The neurosurgeon's method is to record an electrical response in a specific area of the brain resulting from a stimulus to another part of the body. He cautioned that assigning precise anatomical significance to any electrode on the surface of the brain and a distant one of bone or muscle is difficult. However, rapid and accurate identification of sensorimotor cortex in man is possible.
Goldring pointed out that the human brain has been virtually unexplored by classical electrophysiological
