Article Abstract
The ventral tegmental area (VTA), a pivotal brain region of the mesocorticolimbic dopaminergic system, is substantially innervated and modulated by cholinergic projections from the pedunculopontine tegmental nucleus and laterodorsal tegmental nucleus. In this review, we focus mainly on the current findings on VTA cholinergic compositions and functions, including VTA cholinergic innervations and synaptic connectivity, acetylcholine receptor expression and functional characteristics, cholinergic modulation of neuronal activity and dopamine efflux, cholinergic modulation of VTA-mediated behaviors such as reward and addiction, stress and depression, locomotion, etc. Taken together, these findings indicate that cholinergic transmission to the VTA plays an important role in modulation of the VTA circuit, which is implicated in regulation of multiple behaviors.

Dysregulated dopaminergic signaling has been implicated in the pathophysiology of major depressive disorder (MDD) and childhood sexual abuse (CSA), but inconsistencies abound. In a multimodal PET-functional MRI study, harnessing the highly selective tracer [C]altropane, we investigated dopamine transporter availability (DAT) and resting-state functional connectivity (rsFC) within reward-related regions among 112 unmedicated individuals (MDD: n = 37, MDD/CSA: n = 18; CSA no MDD: n = 14; controls: n = 43). Striatal DAT and seed-based rsFC were assessed in the dorsal and ventral striatum and the ventral tegmental area.

Social hierarchies are central to the organizational structure of group-living species, shaping individual physiology, behavior, and social interactions. Dopaminergic (DA) systems, particularly within the ventral tegmental area (VTA) and dorsal raphe nucleus (DR), have been linked to motivation and competitive behaviors, yet their region-specific contributions to social dominance remain insufficiently defined. This study investigated the role of VTA and DR DA neurons in regulating social dominance in sexually naïve male C57BL/6J mice.

Orexin (Orx) is a vital peptide neurotransmitter essential for regulating feeding, sleep-wake cycles, and reward-seeking behavior. Orexinergic neurons are predominantly located in the lateral hypothalamus (LH). However, the precise neural connectivity of these neurons across the brain remains insufficiently characterized.

Reward-predictive cues trigger dopamine release in the nucleus accumbens core (NAc). This signal has long been thought to mediate motivation. However, understanding of dopamine function is complicated by the fact that reward cues not only motivate reward pursuit, but also enable the reward predictions that shape how reward is pursued.
