Document Summary
Evidence concerning the brain functioning that make cognition possible needs its own presentation. Each part of the brain has its own specialized function so that our behaviours, thoughts, and feelings almost invariably depend on the the coordinated action of many brain regions. Capgras syndrome: an initial example rare disorder which seems to be one of the accompaniments to alzheimer"s syndrome. Must use neuroimaging techniques to study the brain. Pet scans tell a great deal about the structure of the brain. Pet scans show a link between capgras syndrome and abnormalities. Another abnormalities is in the frontal lobe, specifically in the right prefrontal cortex. An fmri allows us to track moment-by-moment activity levels in different sites. An fmri of schizophrenic patients reveals diminished activity in the patients" frontal lobes whenever they are experiencing hallucinations. With damage to the frontal love, capgras patients may be less able to keep track of what is real and what is not.
