Norepinephrine: Focus, Stress, Genetics, and Brain Function
Norepinephrine functions both as a brain neurotransmitter that drives focus, attention and motivation, and as a hormone that regulates blood pressure and heart rate during stress. It is produced primarily in the locus coeruleus, where its release activates α1, α2 and β adrenergic receptors to fine‑tune neural circuits. Synthesis proceeds from tyrosine through dopamine via the enzyme DBH, while the norepinephrine transporter (NET) clears about 90% of released NE and is a major pharmacologic target. Genetic variants in DBH, SLC6A2, MAOA and COMT shift baseline NE levels and are linked to conditions such as ADHD, depression, Alzheimer’s, Parkinson’s, ME/CFS and POTS.
