STARVATION and amphetamine both increase behavioural arousal, and have been postulated to act through adrenergic mechanisms in the brain stem. Amphetamine is believed to induce psychomotor excitation by releasing brain catecholamines, blocking their re-uptake from the synapse and mildly inhibiting the action of the catabolizing enzyme, monoamine oxidase1–3.
