The anterior medial prefrontal cortex is also linked to autism and other disorders were people have problems with social interactions. These findings suggest people with such disorders may suffer from an inability to build accurate personality models of others. Further research could not only help diagnose these diseases, but also help treat such disorders, researchers say.
The scientists detailed their findings online March 5 in the journal Cerebral Cortex.
