The Effects of Transcranial Alternating Current Stimulation on Cognitive Function

Bob Greene: I've got brain stimulation in the news from Reinhardt lab at Boston University. He says transcranial alternating current stimulation or tax involves using a brain cap with electrodes to deliver harmless, oscillating current on specific regions of the brain. Greene: The goal is to nudge neurons to fire more rhythmically to alter brain activity. It's based on research that suggests that neurons communicate better when firings are coordinated and can potentially treat neuropsychiatric illnesses.
