What are neurotransmitters?
In the this video you will learn about:
• Serotonin receptors
A neurotransmitter is a brain chemical that relays messages between brain cells and affects emotions, behavior, thoughts and regulates moods. Serotonin, norepinephrine and dopamine are just a few of the neurotransmitters present in the body.
Serotonin exerts its function by binding to receptors, then initiates a series of biochemical reactions finally leading to its physiological functions or behaviors. Serotonin receptors are proteins located on the surface of cells. The serotonin receptor works specifically for serotonin. When it binds to a receptor the signal is amplified inside the cell to begin transcription, enzyme activation, protein synthesis or the release of neuroactive agents. There are many different types of serotonin receptors which have different functions, and there are many different drugs which can increase or decrease the receptor’s function.
