The Serotonin System: A Comprehensive Review

The serotonin system involves a brain chemical called serotonin, which helps regulate mood, sleep, appetite, and overall well-being. Serotonin is produced in the brain and gut, and signals are transmitted between nerve cells through this chemical. Proper functioning of this system is crucial for emotional stability and mental health. Imbalances or disruptions in serotonin levels are linked to conditions like depression and anxiety. Many medications, such as antidepressants, work by increasing serotonin activity to help improve mood and reduce symptoms. Understanding this system better can lead to more effective treatments for mental health disorders.
