Serotonin: All You Need to Know
What is Serotonin?
Serotonin is a neurotransmitter that is found in the human brain, gut, and blood platelets. It is commonly known as the “feel-good” hormone because it plays a key role in regulating mood, sleep, appetite, and memory.
How does Serotonin Work?
Serotonin is released by neurons when they communicate with each other. When serotonin binds to receptors on nearby neurons, it can either excite or inhibit them, depending on the type of receptor.
In the brain, serotonin is involved in regulating a wide range of functions, including:
- Mood regulation
- Sleep regulation
- Appetite regulation
- Memory formation
- Learning
- Attention
In the gut, serotonin helps to regulate digestion and motility. In the blood platelets, serotonin helps to form clots and stop bleeding.
