Locus coeruleus has about 20,000 neurons that produce NE and project to many different regions of the brain. The α1 and α2 receptors have been... WebEpinephrine does not have its own receptors. Instead, since its chemical composition resembles norepinephrine very closely, epinephrine stimulates norepinephrine receptors both in the brain as well as peripherally. In fact, while norepinephrine is primarily a neurotransmitter, epinephrine is primarily a hormone.
