CCK receptors significantly influence neurotransmission in the heart, regulating anxiety, feeding, and locomotion and CCK-A receptors possess a complex regulation of dopamine(neurotransmitter) activity in the brain.
CCK receptors significantly influence neurotransmission in the brain, regulating anxiety, feeding, and locomotion. In the central and peripheral nervous system this receptor regulates satiety and the release of beta-endorphin and dopamine.
