Serotonin and the GI
Serotonin is a psychotropic drug that we hope to use for our next experiment on Hirudo medicinalis and I thought I would look into its effects in the human body. Serotonin is a neurotransmitter (a chemical involved in the transmission of nerve impulses between nerve cells) that's formed in the brain and primarily found in three parts of the body — the brain, the lining of the digestive tract, and in blood platelets. In the brain, serotonin's main effects include improving mood and giving you that "satisfied" feeling from food. It's also thought to help promote sleep and relaxation.
Serotonin is increased by carbohydrate-rich foods and may have different effects in people. Some people may experience a temporary lift in mood after a carbohydrate-rich meal, while others may become relaxed or sleepy. Candy and sweets have the greatest impact but the effects last for one or two hours.
Serotonin increases intestinal motility, by stimulation of 5-HT4 and 5-HT3 receptors in the human: in human beings injected by intravenous route, it increases duodenum and small intestine motility. It also has an emetic effect by stimulation of 5-HT3 receptors. Its administration in high doses has induces gastric ulcerations.
In the leech we hope to see the relationship between feeding and serotonin levels.
