Lesion network mapping of prosopagnosia


  • 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.
