Neural bases of reward anticipation in healthy individuals with low, mid, and high levels of schizotypy

Scientific Reports, 2023
A growing body of research has placed the ventral striatum at the center of a network of cerebral regions involved in anticipating rewards in healthy controls.

A Multivariate Surface-Based Analysis of the Putamen in Premature Newborns: Regional Differences within the Ventral Striatum [PDF]

, 2013
Many children born preterm exhibit frontal executive dysfunction, behavioral problems including attentional deficit/hyperactivity disorder and attention related learning disabilities.

Effects of hippocampal damage on reward threshold and response rate during self-stimulation of the ventral tegmental area in the rat [PDF]

, 1999
The main purpose of this study was to explore the role of the hippocampus in motivated behavior. Rats with bilateral excitotoxic lesions of the hippocampus and controls were trained to lever press for electrical stimulation of the ventral tegmental area.

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

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.

Interspecies Differences in the Connectivity of Ventral Striatal Components Between Humans and Macaques

Frontiers in Neuroscience, 2019
Although the evolutionarily conserved functions of the ventral striatal components have been used as a priori knowledge for further study, whether these functions are conserved between species remains unclear.

Dopamine restores reward prediction errors in old age [PDF]

, 2013
Senescence affects the ability to utilize information about the likelihood of rewards for optimal decision-making. Using functional magnetic resonance imaging in humans, we found that healthy older adults had an abnormal signature of expected value ...

Learning Is Bitter and Sweet in Ventral Striatum [PDF]

Neuron, 2003
AbstractThe ventral striatum (VS) plays a key role in motivationally guided learning. Setlow et al. show that VS neurons encode the significance of cues associated with both aversive and rewarding outcomes and that this neural linkage develops over time in a fashion roughly paralleling the expression of learned behavior.

How the brain represents the reward value of fat in the mouth. [PDF]

, 2009
The palatability and pleasantness of the sensory properties of foods drive food selection and intake and may contribute to overeating and obesity. Oral fat texture can make food palatable and pleasant.
