Neurons That 'Mirror' The Attention Of Others Discovered

ScienceDaily (May 18, 2009) — Whether a monkey is looking to the left or merely watching another monkey looking that way, the same neurons in his brain are firing, according to researchers at the Duke University Medical Center.

"We speculate that the neurons' activity may lie beneath critical social behavior, such as joint attention," said Michael Platt, Ph.D., Duke professor of neurobiology and evolutionary anthropology and senior author of the study published in the Proceedings of the National Academy of Sciences. "If social inputs to the neurons are disrupted, that might contribute to the social deficits seen in autism and other disorders."

People spontaneously follow the gaze of other people, and this joint attention helps promote social bonding, enhance learning, and may even be necessary for the development of language. People who can't do these things are at a decided disadvantage, and may fail to develop normal patterns of social interaction, Platt said.
