User: why do psychologist study the brain and the nervous system?

Note: To learn how they work, to make themselves famous, to help other people, and because they are there (like men climb mountains because they are there). These are a few of the many reasons. [http://answers.yahoo.com/question/?qid=20090108160033AAVd5Tv]

Note: I'm sorry that that wasn't a good answer. Please hold on while I contact an expert.

Weegy: This will make the psychologist aware of the normal activity of the brain and nervous system in comparing with how a person behaves. [ Irregularities on the brain and nervous system would also allow them to make decisions why such behavior is arising on their patients. ]
