Transcript of Prosopagnosia
the inability to recognize faces
Life with Face Blindness
Cannot identify family, friends, or self
Identify people by
Hairstyle (can be problematic)
Relationships severely affected
By: Mary Kate Healy
How We Recognize
Unique system for face processing
Fusiform Face Area
Can identify the parts, but not the whole
Questions to be Answered
What is the full facial recognition process?
What process or region is impaired in those with Posopagnosia?
Genetically based? Which genes?
Is there any hope for improvement of facial recognition?

FFA present- less active/selective
Fewer voxeles/less grey matter
What Causes Prosopagnosia?
Related to Dyslexia?
Similar reduction in gray matter
Deficits caused by neural migration patterns
Impairment in the holistic face process
