Dopamine and Parkinson’s Disease

Serotonin Present in high amounts when awake. Keeps us alert and attentive Affects mood. Depressive & anxious individuals also show sleep disorders Chemical precursor of melatonin – which regulates the biological clock and is present in high concentration at night when asleep Affects perception, cognition and appetite
