Indeed, a major role for nAChRs on dopamine terminals in regulating dopamine release has been demonstrated in rodents [53,54,55,56,57]. This disynaptic mechanism involves acetylcholine released from cholinergic interneurons activating nAChRs on dopamine axons to induce dopamine release. Thus, any changes to cholinergic signaling in striatum might also influence changes in dopamine release. Indeed, a recent […]
