Document Summary

Study conducted where they assigned participants who wanted to learn about meditation as a form of stress reduction, randomly to a meditation group or control group. Central nervous system: includes the brain and the spinal cord. Researchers hypothesize that differences in bodily responses, brain structure, brain activity and salivation, digestion) biochemical activity are all related to individual differences in personality. Galvanic skin response (gsr): measure of skin conductance or how quickly a slight electrical current passes through two points on the skin (measure sweating which is a response of the sympathetic division) Electromyography: estimates the electrical impulses of the muscles contraction and relaxation ray picture of the brain. Originally could only study the brain through autopsies: same technique was once called computer axial tomography (cat) scans brain, the patient is awake and can report on sensations when parts of the brain are stimulated. Similar r technique involves magnetic resonance imaging (mri): radio frequency waves are used instead of x-rays.
