Projection-Target-Defined Effects of Orexin and Dynorphin on VTA Dopamine Neurons

open access: yesCell Reports, 2017
Circuit-specific signaling of ventral tegmental area (VTA) dopamine neurons drives different aspects of motivated behavior, but the neuromodulatory control of these circuits is unclear. We tested the actions of co-expressed lateral hypothalamic peptides,

Stress-Induced Reinstatement of Drug Seeking: 20 Years of Progress [PDF]

open access: yes, 2015
In human addicts, drug relapse and craving are often provoked by stress. Since 1995, this clinical scenario has been studied using a rat model of stress-induced reinstatement of drug seeking.

The Projection Targets of Medium Spiny Neurons Govern Cocaine-Evoked Synaptic Plasticity in the Nucleus Accumbens

open access: yesCell Reports, 2019
Summary: We examine synaptic connectivity and cocaine-evoked plasticity at specific networks within the nucleus accumbens (NAc). We identify distinct subpopulations of D1+ medium spiny neurons (MSNs) that project to either the ventral pallidum (D1+VP) or

A discrete serotonergic circuit regulates vulnerability to social stress

open access: yesNature Communications, 2020
Serotonin is important in depression-like behavior. Here the authors show that dorsal raphe neurons that project to the ventral tegmental area are involved in regulating stress responses in mice.

Stress-Induced Cocaine Seeking Requires a Beta-2 Adrenergic Receptor-Regulated Pathway from the Ventral Bed Nucleus of the Stria Terminalis That Regulates CRF Actions in the Ventral Tegmental Area [PDF]

open access: yes, 2014
The ventral bed nucleus of the stria terminalis (vBNST) has been implicated in stress-induced cocaine use. Here we demonstrate that, in the vBNST, corticotropin releasing factor (CRF) is expressed in neurons that innervate the ventral tegmental area (VTA)

GABAergic and glutamatergic efferents of the mouse ventral tegmental area [PDF]

open access: yesJournal of Comparative Neurology, 2014
ABSTRACTThe role of dopaminergic (DA) projections from the ventral tegmental area (VTA) in appetitive and rewarding behavior has been widely studied, but the VTA also has documented DA‐independent functions. Several drugs of abuse, act on VTA GABAergic neurons, and most studies have focused on local inhibitory connections.

Augmented Cocaine Seeking in Response to Stress or CRF Delivered into the Ventral Tegmental Area Following Long-Access Self-Administration Is Mediated by CRF Receptor Type 1 But Not CRF Receptor Type 2 [PDF]

open access: yes, 2011
Stressful events are determinants of relapse in recovering cocaine addicts. Excessive cocaine use may increase susceptibility to stressor-induced relapse through alterations in brain corticotropin-releasing factor (CRF) regulation of neurocircuitry ...

Programming of Dopaminergic Neurons by Neonatal Sex Hormone Exposure: Effects on Dopamine Content and Tyrosine Hydroxylase Expression in Adult Male Rats

open access: yesNeural Plasticity, 2016
We sought to determine the long-term changes produced by neonatal sex hormone administration on the functioning of midbrain dopaminergic neurons in adult male rats.

Iron accumulation in the ventral tegmental area in Parkinson's disease

open access: yesFrontiers in Aging Neuroscience, 2023
IntroductionThe ventral tegmental area (VTA) is less affected compared to substantia nigra pars compacta (SNc) in Parkinson's disease (PD). This study aimed to quantitatively evaluate iron content in the VTA across different stages of PD in order to help
