Document Summary

Divisions of the nervous system: central nervous system brain and spinal chord: connects peripheral nervous system to brain. Neuropsychological tests verbal tests to get idea of damage to nervous system. Destruction and stimulation techniques researchers do damage and measure results and behaviors. Electrical recording (eeg) measure patterns of electrical activity in brain neurons (large group of neurons) Subdivision of the brain behavioral functions of the brain: forebrain most advanced portion of brain. Cerebrum two large hemispheres that wrap around brain stem. Thalamus like a switchboard (like directing trains into correct track); organizes sensory inputs and sends them to appropriate area; if damaged, causes confusion/hallucinations. Hypothalamus plays roles in motivation and emotion, such as sexual behavior, metabolism. Limbic system coordinates behaviors needed to satisfy motivational/emotional urges: hippocampus form/retrieve memories, amygdala organizes, (part of forebrain)cerebral cortex unmyelinated motivational/emotional response patterns; fear+aggression cells; outermost layer of human brain. Fissures folds in the cerebral cortex.
