Document Summary
The function of the brain is dependent on many interconnected systems. Capgras syndrome: the ability to recognize other individuals, but also being convinced that the people are not who they appear to be (i. e. imposters) Facial recognition depends on proper functioning of two separate systems of the brain that allow: cognitive appraisal, emotional appraisal. Capgras syndrome involves a malfunctioning emotional appraisal system. Damage to the right temporal lobe can result in malfunctioning of the amygdala (emotional evaluator for fear and danger, as well as rewards) Decreased activity in right prefrontal cortex, suggesting decreased ability to distinguish imagined events from real ones. Causes formation of crazy explanations for lack of familiarity. A trillion nerve cells connected to 10,000 others to create 10 million billion connections. Different parts of the brain perform different jobs. Hindbrain: sits directly atop the spinal cord and includes several structures crucial for controlling key life functions, including heartbeats, breathing, posture, balance, alertness.
