Role of the primate ventral striatum as a neural hub bridging option valuation and action selection [PDF]
Nature CommunicationsMaking appropriate decisions relies on the brain’s capacity to evaluate the expected outcomes of available options and select the most rewarding action.

Dopamine Modulates the Processing of Food Odour in the Ventral Striatum [PDF]
Biomedicines, 2022 Food odour is a potent stimulus of food intake. Odour coding in the brain occurs in synergy or competition with other sensory information and internal signals.

Friendship stability in adolescence is associated with ventral striatum responses to vicarious rewards [PDF]
Nature Communications, 2021 A reward-related ventral striatum response is observed when rewards are gained for friends. Here the authors examine how this response changes from childhood to young adulthood, and show that friendship stability in adolescence is associated with ventral

Role of the ventral striatum in developing anorexia nervosa [PDF]
Translational Psychiatry, 2013 Functional imaging data in adult patients with anorexia nervosa (AN) support a dysfunctional signal in the ventral striatum as neural signature of AN. In the present study, development of this signal was investigated with the prediction that a characteristic pattern of ventral-striatal signalling will be shown in response to cues associated with food ...

Deep Brain Stimulation of the Ventral Capsule/Ventral Striatum for Treatment-Resistant Depression [PDF]
Biological Psychiatry, 2009 We investigated the use of deep brain stimulation (DBS) of the ventral capsule/ventral striatum (VC/VS) for treatment refractory depression.Fifteen patients with chronic, severe, highly refractory depression received open-label DBS at three collaborating clinical sites. Electrodes were implanted bilaterally in the VC/VS region. Stimulation was titrated

Aversive counterconditioning attenuates reward signalling in the ventral striatum [PDF]
Frontiers in Human Neuroscience, 2016 Appetitive conditioning refers to the process of learning cue-reward associations and is mediated by the mesocorticolimbic system. Appetitive conditioned responses are difficult to extinguish, especially for highly salient rewards such as food and drugs.

NeuroImage: Clinical, 2022 Background: Growing evidence points towards dysfunction of the ventral striatum as a neural substrate of motivational impairments in schizophrenia. Ventral striatal activity during reward anticipation is generally reduced in patients with schizophrenia ...

Dopamine release in the nucleus accumbens promotes REM sleep and cataplexy
iScience, 2023 Summary: Patients with the sleep disorder narcolepsy suffer from excessive daytime sleepiness, disrupted nighttime sleep, and cataplexy—the abrupt loss of postural muscle tone during wakefulness, often triggered by strong emotion.

Brain and Behavior, 2021 Introduction Rewarding and punishing stimuli elicit BOLD responses in the affective division of the striatum. The responses typically traverse from the affective to the associative division of the striatum, suggesting an involvement of associative ...

Translational Psychiatry, 2021 Obesity is a growing burden to health and the economy worldwide. Obesity is associated with central µ-opioid receptor (MOR) downregulation and disruption of the interaction between MOR and dopamine D2 receptor (D2R) system in the ventral striatum. Weight
