What Does Dopamine Do?
- Mood regulation: Insufficient dopamine can contribute to depression. Meanwhile, some research has found that too much dopamine could cause mania.
- Slows the production of prolactin: Prolactin is involved in both lactation and sexual gratification.
- Regulates sleep: Dopamine helps inhibit the production of melatonin toward the end of a night’s sleep, contributing to wakefulness.
- Regulates attention and memory: Many studies have demonstrated dopamine’s link to attention, memory, and cognition. Disruptions in dopamine have been connected to attention-deficit hyperactivity (ADHD) and schizophrenia,.
