Prosopagnosia is a selective visual agnosia characterized by the inability to
recognize the identity of faces. There are both acquired forms secondary to brain
damage and developmental forms without obvious structural lesions. In this
review, we first discuss the diagnosis of acquired and developmental
prosopagnosia, and the challenges present in the latter case. Second, we discuss
the evidence regarding the selectivity of the prosopagnosic defect, particularly
in relation to the recognition of other objects, written words (another visual
object category requiring high expertise), and voices. Third, we summarize recent
findings about the structural and functional basis of prosopagnosia from studies
using magnetic resonance imaging, functional magnetic resonance imaging, and
event-related potentials. Finally, we discuss recent attempts at rehabilitation
of face recognition in prosopagnosia.
