monoamines

Placebos are thought to act by stimulating the brain's central reward pathways by releasing a class of neurotransmitters called monoamines, specifically dopamine and norepinephrine.

By the late 1950s, the biological psychiatrists had decamped for a new neurochemical territory: not just dopamine but its cousins in a subgroup of monoamines, the catecholamines—which did not include serotonin.

The debates about catecholamines and other monoamines were skirmishes in a larger scientific war—over the hypothesis, first advanced by Betty Twarog, that the brain, like the peripheral nervous system, worked by means of neurochemical transmission.

But then scientists started to find ways to catch the monoamines at work within the brain.

Leading the charge were scientists wielding their knowledge that iproniazid blocked the action of monoamine oxidase MAO, an enzyme that broke down a group of brain chemicals that included serotonin, known collectively as monoamines.

A 2002 University of California animal study indicated that REM sleep was necessary for turning offneurotransmitters and allowing their receptors to "rest" and regain sensitivity which allows monoamines (norepinephrine, serotonin and histamine) to be effective at naturally produced levels.

This is because the natural decrease in monoamines during REM is not allowed to occur, which causes the concentration of neurotransmitters in the brain, that are depleted in clinically depressed persons, to increase.

By inhibiting mitochondrial enzymes that oxidize monoamines serotonin, noradrenaline, dopamine, these drugs increase the bioavailability of the monoamines; presumably, this effect is the basis for their therapeutic action.
