Monoamine Neurotransmitters

Meaning

A critical class of neurotransmitters and neuromodulators derived from a single amino acid, containing one amino group connected to an aromatic ring by a two-carbon chain. Clinically significant examples include dopamine, norepinephrine, epinephrine, and serotonin, which collectively regulate essential functions such as mood, arousal, reward processing, and executive function. Their balance is fundamental to psychological well-being.
