Serotonin is a neurotransmitter that is synthesized, stored, and released by specific neurons in this pathway. It is involved in the regulation of several processes within the brain, including mood, emotions, aggression, sleep, appetite, anxiety, memory, and perceptions.
It is found throughout the brain and the digestive system, and has been implicated in depression, suicide, anxiety, and appetite regulation. Studies show that people with BPD have low levels of serotonin activity, and that this is associated with impulsive aggression (Goodman and New 2000).
