Although some people are fascinated by the brain on its own merits, a growing number are looking to psychology in order to better their own study skills and cognitive performance. Modern brain research is being done in a variety of fields.  Experimental psychologists at research universities are developing theories about the social and cognitive aspects of the brain and proving these by running tests on college freshmen.  Neuroscientists use imaging techniques along with visual or auditory stimuli to measure and record changes within the brain.
