Document Summary

Psychologists study the brain using many different methods. Scientists can study the anatomy of cadavers" brains to attempt to draw conclusions about differences in brain morphology and behavior. Lesions, or damage, to the brain can provide clues as to the function n of the damaged area of the brain by examining changes in behavior and physical abilities after the lesion occurs. Electroencephalography (eeg) is a technique that records the electrical activity produced by the brain"s neurons through the use of electrodes that are placed around the research participant"s head. Functional magnetic resonance imaging (fmri) is a type of brain scan that uses a magnetic field to create images of brain activity in each brain area. Detects changes in blood flow in the brain. Homeostasis is the natural balance in the body"s systems. A gland in the endocrine system is made up of groups of cells that function to secrete hormones.
