Dopamine D-3 receptors regulate GABA(A) receptor function through a phospho-dependent endocytosis mechanism in nucleus accumbens

, 2006
The dopamine D-3 receptor, which is highly enriched in nucleus accumbens (NAc), has been suggested to play an important role in reinforcement and reward.

The Brain‐Age Gap in Pediatric Dystonia: Neuroanatomical Deviations Inform Deep Brain Stimulation Outcomes

Movement Disorders, EarlyView.
Abstract Background Dystonia in children is a heterogeneous condition with variable response to deep brain stimulation (DBS). Brain‐age gap, a machine learning‐derived metric of structural deviation from norm, may capture signatures that differentiate underlying biotypes and predict outcomes.

Perspective: Depression in Persons with Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Depression is a prevalent and disabling syndrome characterized by sustained sadness and/or anhedonia, as well as cognitive and physical symptoms. In Parkinson's disease (PD), depression is both common and clinically challenging due to overlapping symptoms and complex etiologic interactions. Major depressive disorder occurs in approximately 17%

Associations of cannabis use, tobacco use and co‐use with brain volume: A systematic review and meta‐analysis

Addiction, EarlyView.
Abstract Background and aims Cannabis is the most widely used illicit drug worldwide and is often co‐used with tobacco, the leading cause of preventable death. Although cannabis and tobacco have distinct neurobiological actions, their associations with brain volumes are unclear.

Hypoactivity and neurochemical alterations in the basal ganglia of female Sprague-Dawley rats after repeated exposure to atrazine

Frontiers in Toxicology
The herbicide atrazine (ATR) has been one of the most widely used herbicides worldwide. However, due to its indiscriminate use, it has been considered an environmental contaminant. Several studies have classified ATR as an endocrine disruptor, and it has

Nucleus accumbens response to gains in reputation for the self relative to gains for others predicts social media use

Frontiers in Human Neuroscience, 2013
Our reputation is important to us; we’ve experienced natural selection to care about our reputation. Recently, the neural processing of gains in reputation (positive social feedback concerning one’s character) has been shown to occur in the human ventral

Cholecystokinin and neurotensin peptides as modulator of neurotransmitter release in the nucleus accumbens

, 2008
The present article shortly reviews the biochemical and neurochemical results showing the role that cholecystokinin (CCK) and neurotensin (NT) neuropeptides play in the control of dopaminergic and GABAergic signalling in the rat nucleus accumbens and ...

Brain reward function in young people with cannabis use disorder: A functional magnetic resonance imaging study

Addiction, EarlyView.
Abstract Background and Aims Cannabis use disorder (CUD) affects ~50 million people globally. Neuroscientific theories suggest that a blunted neural response to non‐drug rewards is a hallmark of substance use disorders; however, this remains untested in CUD. The current study tested whether brain reward system responses to the anticipation and feedback
