Document Summary

This is due to the place in the brain used to detect faces. Neuroimaging techniques have been developed in the last few decades and allow researchers to take high-quality, 3-d images of living brains without disturbing the person: mri, fmri, pet. In the case of capgras syndrome the amygdala which is important for triggers of safety and danger is damaged, showing why they do not feel safe. They also have damage in the prefrontal cortex which is active when a person is planning or doing a careful analysis: this is diminished and the person sometimes doesn"t know the difference between internal events and external. The amygdala and prefrontal cortex are both at fault: don"t recognize faces or feel safe. The brain is 3-4 pounds and is about the size of a melon: there are 10 million billion connections in the brain. Damage to different parts of the brain result in different outcomes.
