  "summary": "The nucleus accumbens (NAc) plays a critical role in reward-related behaviors, which exhibit diurnal variations. Cholinergic interneurons (CINs) are the primary source of acetylcholine within the NAc and regulate local dopamine (DA) signaling through nicotinic acetylcholine receptors (nAChRs). Although there are diurnal variations in NAc dynamics, little is known about whether CIN activity and…",
