Document Summary
Capgras syndrome: a psychological delusion in which a person thinks people in his life are imposters (for ex: thinks father isn"t actual father, but looks like him) This occurs by disassociation between areas in the brain that control vision and emotion. The brain is largely symmetrical around the midline. Most structures come in pairs: one left, one right endocrine system; linked to emotion and reward. Amygdala: neural centers in the limbic system linked to emotion. Hippocampus: a structure in the limbic system linked to memory. Corpus callosum: axon fibers connecting two cerebral hemisphere. Thalamus: relays messages between lower brain centers and cerebral cortex. Hypothalamus: controls maintenance functions such as eating; helps govern. Spinal cord: pathway for neural fibers traveling to and from brain; controls simple. Cerebral cortex: ultimate control and information-processing center (80% of brain reflexes volume in humans) The prefrontal cortex: brain region particularly concerned with social phenomena (ex: following norms)
