Motivation and the Brain Paper
Neuroscience and psychology seem to have been working together to try to understand how and why certain behaviors transpire in a person’s personality, and what makes or motivates a person to do the things they do. One of the most analyzed wonders that mark motivation, the thought developments, and the social interaction, is the analysis of drug obsession. Through advance forms of scanning the brain with imaging equipment like positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) have advanced the knowledge of drug addiction and how the brain is affected (Volkow, Fowler, & Wang, 2003,para 2). This paper will examine the brain structures and functions, the influence of extrinsic and intrinsic factors to abstain from drug use and the heredity and environmental factors on the motivation used to refrain from drug use.

The brain is the control station of the body. It is in control of everything you do, it even is hard at work while you sleep. Just like any other control or command center, the many parts that make up the brain must work together as a team. When drugs come into the brain, they interrupt the work and change how the brain then performs its job. These alterations can lead to compulsive drug use. Physical changes within the brain are linked to chronic substance abuse having a major impact on the brains functioning and emotional disarrays. Drugs are chemicals, which access the brains communication system and interfere with the method nerve cells send, receive and process information. “Some drugs can change the brain in ways that last long after the person has stopped taking drugs, maybe even permanently. This is more likely when a drug is taken repeatedly” (NIDA, 2011,para 6). Some drugs can copycat a natural neurotransmitter sending abnormal messages through the brain. They can also causes nerve cells to discharge excessive amounts which can eventually cause confusion on the...
