Claim: 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.
Evidence: 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.
