Prosopagnosia is associated with damage to which hemisphere?

• A. Parietal
• B. Temporal
• C. Left
• D. Right

Answer: (D)

Face recognition relies on a right-hemisphere network, with a key node called the fusiform face area in the right fusiform gyrus (part of the occipitotemporal region). When this right-sided area is damaged, the brain’s ability to identify and distinguish familiar faces is disrupted, producing prosopagnosia. The left hemisphere and parietal regions aren’t the main players in this specialized facial-identity pathway, so lesions there don’t typically cause the same selective deficit. The right temporal fusiform area is the critical locus, so injury to the right hemisphere reliably disrupts facial recognition.
