An approach for identifying brainstem dopaminergic pathways using resting state functional MRI. [PDF]

, 2014
Here, we present an approach for identifying brainstem dopaminergic pathways using resting state functional MRI. In a group of healthy individuals, we searched for significant functional connectivity between dopamine-rich midbrain areas (substantia nigra;

Neurochemical organization of the ventral striatum’s olfactory tubercle [PDF]

Journal of Neurochemistry, 2020
AbstractThe ventral striatum is a collection of brain structures, including the nucleus accumbens, ventral pallidum and the olfactory tubercle (OT). While much attention has been devoted to the nucleus accumbens, a comprehensive understanding of the ventral striatum and its contributions to neurological diseases requires an appreciation for the complex

Differential functions of ventral and dorsal striatum [PDF]

Brain, 2015
Sir, The case study by Vo and colleagues (2014) aims to address the differential roles of ventral versus dorsal striatum in learning, specifically, whether they are essential for learning or simply involved in it. The authors reported a dissociation between action-value (based on the outcomes, values will be assigned to actions) and stimulus-value ...

Mesolimbic opioid-dopamine interaction is disrupted in obesity but recovered by weight loss following bariatric surgery

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

Ventral Striatum Lesions Enhance Stimulus and Response Encoding in Dorsal Striatum [PDF]

Biological Psychiatry, 2014
The development of addiction is thought to reflect a transition from goal-directed to stimulus-response driven behavior, functions attributed to ventral (VS) and dorsal striatum (DS), respectively. In line with this theory, neuroadaptations that occur during prolonged drug use progress from VS to DS.

Predictors of Hypomania During Ventral Capsule/Ventral Striatum Deep Brain Stimulation [PDF]

The Journal of Neuropsychiatry and Clinical Neurosciences, 2016
Deep brain stimulation (DBS) of the ventral capsule/ventral striatum (VC/VS) is a novel therapy for neuropsychiatric disorders. Hypomania is a known complication of VC/VS DBS, but who is at risk is less understood. Factors such as family history, combined with details of DBS programming, might quantify that risk.

Reward Anticipation in Ventral Striatum and Individual Sensitivity to Reward: A Pilot Study of a Child-Friendly fMRI Task. [PDF]

PLoS ONE, 2015
Reward processing has been implicated in developmental disorders. However, the classic task to probe reward anticipation, the monetary incentive delay task, has an abstract coding of reward and no storyline and may therefore be less appropriate for use ...

Illustrated Review of the Ventral Striatum’s Olfactory Tubercle [PDF]

Chemical Senses, 2016
Modern neuroscience often relies upon artistic renderings to illustrate key aspects of anatomy. These renderings can be in 2 or even 3 dimensions. Three-dimensional renderings are especially helpful in conceptualizing highly complex aspects of neuroanatomy which otherwise are not visually apparent in 2 dimensions or even intact biological samples ...

Cocaine exposure shifts the balance of associative encoding from ventral to dorsolateral striatum

Frontiers in Integrative Neuroscience, 2007
Both dorsal and ventral striatum are implicated in the "habitization" of behavior that occurs in addiction. Here we examined the effect of cocaine exposure on associative encoding in these two regions.
