Brain area that recognises facial expressions found
Researchers, including one of Indian-origin, have pinpointed the area of the brain responsible for recognising human facial expressions. Researchers from Ohio State University in the U.S. used functional magnetic resonance imaging to identify a region of pSTS as the part of the brain activated when test subjects looked at images of people making different facial expressions. “That suggests that our brains decode facial expressions by adding up sets of key muscle movements in the face of the person we are looking at,” said Aleix Martinez from Ohio State University. “That is a very powerful development, because it suggests that the coding of facial expressions is very similar in your brain and my brain and most everyone else’s brain,” said Mr. Martinez. Researchers, including Ramprakash Srinivasan from Ohio State University placed 10 college students into an fMRI machine and showed them more than 1,000 photographs of people making facial expressions.
