Final answer:
Prosopagnosia, or face blindness, is the inability to recognize faces due to damage or developmental issues in the fusiform gyrus. Those affected can use other cues such as voice and unique features to identify individuals.
Step-by-step explanation:
Deficit from damage to Fusiform Gyrus, a patient cannot recognize familiar faces, a condition known as prosopagnosia or face blindness. This sensory deficit is particularly damaging socially as it prevents recognition of even the most familiar individuals, including family members and oneself. The fusiform gyrus, specifically the anterior part in the temporal lobe, is linked to visual stimuli recognition and association with memories. Damage or developmental issues in this region can lead to prosopagnosia. Despite this challenge, individuals with prosopagnosia may rely on other cues like the sound of a voice, unique facial features, or hair color to recognize people.
