Norepinephrine (INN) (abbreviated norepi or NE) or noradrenaline (BAN) (abbreviated NA or NAd) is a catecholamine with multiple roles including as a hormone and a neurotransmitter.[5] As a stress hormone, norepinephrine affects parts of the brain where attention and responding actions are controlled.
