Periaqueductal efferents to dopamine and GABA neurons of the VTA. [PDF]

open access: yesPLoS ONE, 2018
Neurons in the periaqueductal gray (PAG) modulate threat responses and nociception. Activity in the ventral tegmental area (VTA) on the other hand can cause reinforcement and aversion.

The Role of Dopaminergic VTA Neurons in General Anesthesia. [PDF]

open access: yesPLoS ONE, 2015
Recent studies have demonstrated that the central dopaminergic system is implicated in the mechanism underlying general anesthesia. Here, we investigated whether dopaminergic ventral tegmental area (VTA) neurons participate in general anesthesia ...

Nicotinic Cholinergic Receptors in VTA Glutamate Neurons Modulate Excitatory Transmission

open access: yesCell Reports, 2018
Summary: Ventral tegmental area (VTA) glutamate neurons are important components of reward circuitry, but whether they are subject to cholinergic modulation is unknown.

Noradrenergic signaling in the VTA modulates cocaine craving

open access: yesAddiction Biology, 2017
Exposure to drug-associated cues evokes drug-seeking behavior and is regarded as a major cause of relapse. Conditional stimulus upregulates noradrenaline (NA) system activity, but the drug-seeking behavior depends particularly on phasic dopamine ...

Untangling the multifaceted VTA responses to stress

open access: yesTrends in Neurosciences
Stress has profound impacts on the ventral tegmental area (VTA). However, the complex and opposing effects of stress on the VTA have limited our ability to reach a clear understanding of how adaptation of the VTA can drive behavior following stress.

Peripheral nerve injury-induced alterations in VTA neuron firing properties

open access: yesMolecular Brain, 2019
The ventral tegmental area (VTA) is one of the main brain regions harboring dopaminergic (DA) neurons, and plays important roles in reinforcement and motivation.

Hederagenin Attenuates Morphine Addiction via GABAA1-Mediated Modulation of Ca<sup>2</sup> <sup>+</sup>-CaMK-CREB Signaling in Ventral Tegmental Dopaminergic Neurons. [PDF]

open access: yesAdv Sci (Weinh)
Hederagenin is identified as a GABAA1‐targeting natural compound that suppresses morphine‐associated reward by restraining Ca2+–CaMK–cAMP–CREB signaling in ventral tegmental dopaminergic neurons. RVG29‐modified liposomal delivery further enhances brain accumulation and behavioral efficacy, providing a mechanistically defined strategy for natural ...

A Critical Time Window of Neocortex Modulation for Remote Fear Memory in Rats and Humans. [PDF]

open access: yesAdv Sci (Weinh)
This study identifies a delayed consolidation window around 18 h after fear learning in the mPFC essential for remote fear memory. VTA dopaminergic input during this window sustains remote memory in rats, while non‐invasive stimulation of homologous human mPFC at the corresponding time selectively weakens remote but not recent fear memory, revealing a ...

Nucleus Accumbens and Ventral Tegmental Area Functional Connectivity as a Marker of Reward Sensitivity in Infancy. [PDF]

open access: yesDev Sci
ABSTRACT Early functional connectivity within the brain's reward circuitry may provide insight into the developmental origins of individual differences in pleasure and motivation. This study examined resting‐state functional connectivity between two key reward‐related regions, the nucleus accumbens (NAc) and ventral tegmental area (VTA), in 94 one ...
