Brain activity in the fusiform face area on the right side of the brain showed no difference in those with face blindness compared to those without the condition. However, researchers found those with prosopagnosia had reduced activity in a corresponding area on the left side of the brain.
Prosopagnosia, or "face-blindness", involves an entire network, not just one area of the brain. The findings may shed light on poor facial processing abilities associated with autism.
A new study illustrates how individuals with face blindness are still able to recognize other people's movements.
