Widespread brain connections enable face recognition
Remembering a familiar face engages a wider network of brain regions than previously thought, according to a study of healthy men and women published in JNeurosci.
First described in JNeurosci more than 20 years ago, the fusiform face area is a major component of a group of brain regions specialized for face perception known as the face network. The ability to recognize familiar faces varies, from individuals who are "face blind" to those with above-average facial recognition.
Michal Ramot and colleagues at the National Institute of Mental Health found that strength of connections within the face network were not associated with memory for faces.
By taking a broader view of the brain, the researchers demonstrate connectivity between the face network and other circuits involved in memory and processing of social, visual, and auditory information predicted participants' performance on a facial memory task.
These findings suggest face recognition involves the integration of facial features with the social and multisensory context in which they appear in everyday life.
