Norepinephrine
Norepinephrine
A neurohormone is a hormone that is secreted and circulated by neurosecretory cells into the blood. It stimulates neural mechanisms when activated by neural stimuli.
The majority of CNS stimulants are chemically similar to the neurohormone norepinephrine, and simulate the traditional "fight or flight" syndrome associated with sympathetic nervous system arousal.
