This is especially so when you consider that serotonin is an amino acid which normally causes the body to have a feeling of well being; it is an chemical that keep moods under control by regulating body processes such as sleep, relaxation, anxiety and depression (Patterson et al). All these feelings and body processes are dependent on the state of the brain which is responsible for instructing body cells; thus, we can see how serotonin not only influences the state of the brain but the implications it has as well on addictive behaviors among individuals.
The way that the brain works in secretion of serotonin is very complicated since it really does not have to maintain balanced levels of serotonin in the body strictly speaking similar to how many body processes are regulated. This is because the brain is constantly assessing whole range of situations to determine whether to increase, reduce or maintain balanced level of serotonin within the body at any given time. For instance the brain can automatically reduce the secretion of serotonin in order to inhibit a particular action that it deems necessary such as safety (Patterson et al).
