Serotonin, which has been shown to influence many of the brains cells, is made through a biochemical process in the brain but for the most part is found in the digestive tract and in the blood platelets. As a neurotransmitter, Serotonin is responsible for feelings of happiness, contentment and overall mood. When concentration levels of serotonin are high then feelings of happiness ensue. When levels of Serotonin are low an individuals overall mood decreases as they become irritable and sad. Additionally 5-HTP, which can act as a serotonin precursor to stimulate the secretion of serotonin production in the brain. If the levels of serotonin absorbed during reuptake are extreme then this also can lead to feelings of sadness. As a result, serotonin can be linked to have influences on different behaviors such as, but not limited to, overall mood. The overall composition of serotonin is essentially a combination of tryptophan hydroxylase and tryptophan, which makes 5-hydoxytryptamine, also known as serotonin.

What are the effects of different levels of serotonin?

How do ergotropic and trophotropic metabolic pathways differ?
Pam Grout, Alternative/complementary Medicine, answered
Let's put it this way. If you were a boss and you were hiring one of these two metabolic pathways, you'd definitely want to offer the ergotrop more money. The ergotropic mode always gets the job done. It burns up fat. The trophotrop, on the other hand, is kinda lazy. It prefers to store fat. Its thinking is "Why should I carry this fat out of the body when I can just as easily stick it in a cell?" If there aren't enough cells, it will even make new ones to dump that fat in. When you don't get enough oxygen, your body automatically hires the work-shirking metabolism. But when you breathe deeply, you get to welcome the hardworking metabolism to your team.

How can the deep brain stimulation electrode help?
Discovery Health answered
Because Parkinson's disease disrupts the electrical flow of brain activity throughout the basal ganglia, implanting a deep brain stimulation (DBS) electrode can allow electrical pulses to be delivered that counteract the abnormal brain activity. The alteration achieved by the DBS implant can decrease disease symptoms.
The electrode does its work by targeting one of several structures in the basal ganglia.
For Parkinson's disease, the target is most commonly the subthalamic nucleus (STN).
When a deep brain stimulation electrode is implanted in the STN, it sends out pulses of electricity, which modifies its behavior. By changing the behavior of the STN, the electrode ultimately alters all of the brain activity normally affected by the STN. As a result, the DBS electrode is very influential because the STN is one of several structures that all work together in the basal ganglia.
