Resumen de Face-blind people miss a brain 'hub'
Galia Avidan at Ben-Gurion University of the Negev, Israel, and her colleagues investigated the causes of prosopagnosia or face blindness, a disease which lead to the difficulty of identifying faces which can lead to social anxiety and depression and can go often undiagnosed for years. Galia scanned the brains of 10 adults who had reported lifelong problems with face processing, as well as 10 adults without the condition. Researchers found that regions towards the front of the brain form a "hub" that is highly connected with other regions, including those at the back that process more basic visual information where people with prosopagnosia missed the hub-like behavior and had greater connections in the back portions of the brain and states that the hyper-connectivity at the rear of the brain might be a compensatory mechanism as they rely on more visual information.
