PSYB57H3 Chapter Notes - Chapter 2: Functional Magnetic Resonance Imaging, Capgras Delusion, Transcranial Magnetic Stimulation
Document Summary
Capgras syndrome a relatively rare disorder, resulting from specific forms of brain damage, in which the afflicted person recognizes the people in his or her world but denies that they are who they appear to be. Instead, the person insists, these familiar individuals are well-disguised impostors. Facial recognition involves two separate systems: cognitive appraisal: understanding that the other person is recognized, global emotional appraisal: the warm response to familiarity. These two together results in: of course you"re who you are. The emotional appraisal is disrupted in this syndrome leading to the intellectual identification without the familiarity response. Neuroimaging techniques allow researchers to take high-quality, 3-d pictures of living brains. Current studies rely on mri scans, before researchers relied on pet scans. Capgras patients also have damage in the right prefrontal cortex the outer surface (cortex) of the front most part of the brain.
