Making connections for face recognition

Nature Neuroscience

2008년11월24일

The connectivity among face processing areas in the brain is disrupted in people born with prosopagnosia, a disorder of impaired face recognition ability, reports a study published online this week in Nature Neuroscience.

Previous work had suggested that the size and activity levels of interconnected face processing areas in prosopagnosics’ brains are relatively normal. Cibu Thomas and colleagues now ask whether a disruption of the connectivity among these areas could underlie the disorder. Face processing areas are connected by two major tracts of white matter, but the team find that in prosopagnosics, the structural integrity of both of these tracts is reduced. Other tracts connecting surrounding regions are unaffected in prosopagnosics.

Performance on a face recognition task correlates with the structural integrity of these connections, suggesting that these differences underlie this unique behavioural impairment.
