Psychology / Unit 2 Psych 0170 short lesson, about 20 seconds
Antagonists
Captions available
The idea
An antagonist is a substance that decreases a neurotransmitter's activity, usually by occupying its receptor without activating it.
In practice
A drug that binds dopamine receptors without triggering them prevents dopamine from acting there.
Where people slip
Antagonist and agonist describe an effect on a system, not a moral status. Both appear in useful medications.
