Brain area that recognises facial expressions found

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. Researchers, including one of Indian-origin, have pinpointed the area of the brain responsible for recognising human facial expressions. The area is on the right side of the brain behind the ear, in a region called the posterior superior temporal sulcus (pSTS). Researchers from Ohio State University in the U.S. used functional magnetic resonance imaging (fMRI) 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. They discovered that neural patterns within the pSTS are specialised for recognising movement in specific parts of the face. One pattern is…
