Researchers pinpoint individual brain cells that respond to particular people, objects
CHICAGO — The Halle Berry fan club is expanding one brain cell at a time. By eavesdropping on the activity of single neurons in the human brain, scientists have figured out which brain cells go wild for superstars such as the popular actress. And the newest research shows that people can activate those cells selectively.
“This study is the first demonstration of humans’ ability to control the activity of single neurons,” the researchers wrote in a summary of their study. The results, presented October 19 at the Society for Neuroscience’s annual meeting by Moran Cerf of the California Institute of Technology in Pasadena, may help researchers understand how each cell in the brain sees and responds to the world.
