For years, doctors have been puzzled by the condition known as Capgras Delusion, in which a person
believes that his or her family members and friends have been replaced by impostors. Neurologist V. S.
Ramachandran has suggested that Capgras Delusion might be a result of a disconnection between the
"fusiform face area," a region of the brain involved in face perception, and the amygdala, which is involved
in the emotional responses to familiar faces. Ramachandran hypothesized that, due to the severing of the
connection between the face recognition area and the amygdala, Capgras patients just don't feel the
emotional response they expect to feel upon seeing a family member or friend-leading them to believe
that the family member or friend they see must be an impostor.
