- Recent studies have revealed a correlation between prognosis in heart failure and plasma levels of such neurohormones as endothelin, norepinephrine and renin, among others.
- It is called GABA gamma-aminobutyric acid and it calms the brain from too much of the neurotransmitters epinephrine and norepinephrine. The UltraMind Solution
- He then went on to study the release of norepinephrine from the adrenergic neurons in the ear artery by cholinergic agonists acting on prejunctional nicotinic receptors. Robert F. Furchgott - Autobiography
- This results in rebound of the previously suppressed stimulatory transmitters (serotonin, norepinephrine and dopamine).
- Norepinephrine and serotonin may be excitatory or inhibitory, but they are functionally inhibitory on pain transmission; glutamate is the other important excitatory neurotransmitter.
