Takeaway
Prosopagnosia is associated with a single brain network that encompasses positive connectivity to the right fusiform face area (FFA) and negative connectivity to the left frontal regions.
Why this matters
Typically, prosopagnosia is caused by damage to the FFA; however, lesions to other areas of the brain can cause prosopagnosia, suggesting a facial recognition brain network.
The regions involved in this brain network are unknown; using lesion network mapping to identify these regions may lead to improvements in clinical treatments for prosopagnosia.
