Topic 2.5
Why do opioids like morphine cause pain relief and intense feelings of pleasure?
By inhibiting GABA's inhibitory function, they allow for more dopamine to be released.
By enhancing acetylcholine function, they promote relaxation and reduce anxiety.
By binding to opioid receptors in neurons, they mimic endorphins' natural effects.
By acting as glutamate antagonists, they suppress pain signals sent to the brain.
