serotonin systems

Serotonin systems involve a brain chemical called serotonin that influences mood, sleep, appetite, and emotional well-being. Serotonin is produced in certain brain areas and transmitted between nerve cells via specialized receptors. It helps regulate how we feel, think, and respond to stress. Imbalances in serotonin levels or receptor function are linked to conditions like depression, anxiety, and sleep disorders. Many medications for these conditions aim to adjust serotonin levels or receptor activity to help restore balance, improving mood and overall mental health.
