Document Summary

Mri: magnetic resonance imaging: provides a high resolution image of the human brain, static: does not indicate which areas of the brain are active during a specific task, expensive, figure above is from an mr image. Eeg(electroencephalogram)/evoked potentials: electrodes attached to the surface of the scalp, provides an indication of the electrical activity of the brain (eeg), when a stimulus is presented, evoked potentials can be used to measure the brain"s response to these stimuli, cheap, unlike the fmri, its resolution is very poor (we cannot easily tell where the electrical activity is being generated in the brain. Divisions of the nervous system: peripheral nervous system, autonomic, sympathetic, provide energy increase heart beat, respiration, dilate of skeletal muscles; constrict arteries of skin; inhibit digestive system, parasympathetic, conserve energy slow heart beat, etc, somatic, central nervous system, the spinal cord, the brain.
