Neurotransmitter Theory

Neurotransmitter theory suggests that our thoughts, feelings, and behaviors are influenced by chemicals called neurotransmitters in the brain. These molecules transmit signals between nerve cells (neurons), playing a crucial role in mood regulation, cognition, and physical functions. Imbalances or irregularities in neurotransmitter levels—such as serotonin, dopamine, or norepinephrine—are thought to contribute to mental health conditions like depression, anxiety, or schizophrenia. Treatments often aim to restore these chemical balances through medication, therapy, or lifestyle changes, helping improve mental well-being and functioning.
