Aversion or Salience Signaling by Ventral Tegmental Area Glutamate Neurons

open access: yesiScience, 2018
Summary: Ventral tegmental area (VTA) neurons play roles in reward and aversion. The VTA has, in addition to dopamine neurons, glutamatergic neurons expressing VGluT2.

Nicotine inhibits the VTA-to-amygdala dopamine pathway to promote anxiety

open access: yes, 2021
International audienceNicotine stimulates dopamine (DA) neurons of the ventral tegmental area (VTA) to establish and maintain reinforcement. Nicotine also induces anxiety through an as yet unknown circuitry.

Ventral tegmental area integrity measured with high-resolution 7-Tesla MRI relates to motivation across depression and anxiety diagnoses

open access: yesNeuroImage, 2022
The ventral tegmental area (VTA) is one of the major sources of dopamine in the brain and has been associated with reward prediction, error-based reward learning, volitional drive and anhedonia.

Sweetspot Mapping in Deep Brain Stimulation: Strengths and Limitations of Current Approaches

open access: yesNeuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Open questions remain regarding the optimal target, or sweetspot, for deep brain stimulation (DBS) in, for example, Parkinson's disease. Previous studies introduced different methods of mapping DBS effects to determine sweetspots. While having a direct impact on surgical targeting and postoperative programming in DBS, these methods ...

Increased functional coupling between VTA and hippocampus during rest in first-episode psychosis [PDF]

open access: yes, 2021
Animal models suggest that interactions between the hippocampus and ventral tegmental area (VTA) underlie the onset and etiology of psychosis. While a large body of research has separately characterized alterations in hippocampal and VTA function in ...

Determination of circuit-specific morphological adaptations in ventral tegmental area dopamine neurons by chronic morphine

open access: yesMolecular Brain, 2019
Chronic opiate exposure induces neuroadaptations in the mesocorticolimbic system including ventral tegmental area (VTA) dopamine (DA) neurons, whose soma size is decreased following opiate exposure.

Local Field Potential‐Based Programming: A Proof‐of‐Concept Pilot Study

open access: yesNeuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Programming deep brain stimulation (DBS) is still based on a trial‐and‐error approach, often becoming a time‐consuming process for both treating physicians and patients. Several strategies have been proposed to streamline DBS programming, most of which are preliminary and mainly address Parkinson's disease, a condition readily ...

Two-Pronged Control of the Dorsal Raphe by the VTA [PDF]

open access: yesNeuron, 2019
In this issue of Neuron, Li et al. (2019) distinguish two separable GABAergic projections from the ventral tegmental area (VTA) to the dorsal raphe nucleus (DRN), with differential μ-opioid receptor regulation, each targeting different postsynaptic neurons and promoting opposing behavioral states.

Anatomical Templates of the Midbrain Ventral Tegmental Area and Substantia Nigra for Asian Populations

open access: yesFrontiers in Psychiatry, 2018
Increasing evidence shows that the midbrain dopaminergic system is involved in various functions. However, details of the role of the midbrain dopaminergic system in these functions are still to be determined in humans.

Cognitive Outcome After Deep Brain Stimulation for Refractory Obsessive–Compulsive Disorder: A Systematic Review

open access: yesNeuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Introduction Deep brain stimulation (DBS) is an effective treatment for refractory obsessive–compulsive disorder (OCD). Neuropsychological assessment contributes to DBS treatment in several ways: it monitors the cognitive safety of the treatment, identifies beneficial or detrimental cognitive side effects and it could aid to explain ...
