An empirical study. A neurotransmitter produced in the brain
Also called 5-hydroxytryptamine Can be found in the pineal gland, blood platelets, the digestive tract, and the brain
Made in a biochemical conversion process Serotonin modulates neural activity and is thought to regulate emotional reactions

When the level of serotonin is too low
-It allows wild fluctuations in other neural activity
*Producing symptoms of depression Certain types of depression are Serotonin Depression because they are caused by imbalances of serotonin.

Serotonin depression symptoms can affect depressive disorders, bipolar disorders, anxiety and eating disorders. The common type of serotonin depression is caused by a genetic defect in the brain’s serotonin receptors
-These are called 5HTT receptor sites.

These receptor sites are too short and too quick to absorb the serotonin.
-Therefore they are unable to release serotonin back into the neural
pathway again.
*Results in a shortage of serotonin. It plays a role in the causes of depression, bipolar disorder, anxiety and sexuality. High levels of serotonin may cause the following:
• Serotonin syndrome
○ Death The serotonin occurs when two medicines which affect the body's serotonin amount are taken at the same time. These two drugs clash with each other and causes the serotonin syndrome.

Symptoms of the serotonin syndrome are:
• Agitation or restlessness
• Diarrhoea
• Fast heartbeats
• Hallucinations
• High body temperature
• Loss of coordination
• Nausea
• Overactive reflexes
• rapid changes in blood pressure
• Vomiting
• heavy sweating
• Fever
• Shivering
