But scientists are now exploring a question that is, well, mind-boggling: Can low-voltage doses of electricity, transmitted through hair, skin and skull directly into particular regions of the brain, make already healthy people sharper and more alert?Īron Barbey, a 39-year-old neuroscientist at the University of Illinois, is a leader in this research, though he is excruciatingly cautious about its prospects. ![]() That the brain generates a bit of its own electricity, which can be detected by an electroencephalogram, or EEG, is well established, as is the fact that some neurosurgeons today sometimes use hair-thin electrodes to stimulate deep brain structures and stop Parkinson’s tremors.
