Study establishes extent of human brain excited by specific
Researchers at the Stanford University School of Medicine have determined the amount of human brain tissue that is excited by a given dose of electrical stimulation.

“We have, for the first time in humans, established a dose-response curve that applies to electrical stimulation rather than to drugs,” said Josef Parvizi, MD, PhD, associate professor of neurology and neurological sciences.

The findings, described in a study published online Dec. 8 in Neuron, may guide the therapeutic application of electrical brain stimulation via surgically implanted, current-emitting devices....
