[23] Actions of adrenaline and noradrenaline are responsible for the fight or flight response , characterised by a quickening of breathing and heart rate, an increase in blood pressure ...

[1] It is one of three endorphins that are produced in humans, the others of which include α-endorphin and γ-endorphin. [2]
One such region is the nucleus accumbens—a key part of the brain’s reward system that’s fueled by dopamine, a chemical that Wise fondly refers to as “the slutty neurotransmitter” because ...
