- Cognitive functions such as memory and learning
Dopamine
Dopamine is another critical neurotransmitter that plays a vital role in the brain's reward system.It is associated with pleasure, motivation, and reinforcement of behaviors. When we engage in activities that bring us joy or satisfaction, dopamine levels increase, reinforcing those behaviors. However, imbalances in dopamine levels can lead to various mental health issues, including:
- Depression
- Schizophrenia
- Addiction
Norepinephrine
Norepinephrine functions both as a neurotransmitter and a hormone. It is involved in the body's fight-or-flight response, preparing us to react to stressful situations.In terms of mood regulation, norepinephrine helps maintain alertness and focus. Low levels can contribute to symptoms of depression and attention disorders.Understanding these neurotransmitters is crucial when discussing how St. John's Wort may influence brain health.
