Dopamine Modulates the Processing of Food Odour in the Ventral Striatum [PDF]

open access: yesBiomedicines, 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.

Neural correlates of reward processing: Functional dissociation of two components within the ventral striatum [PDF]

open access: yesBrain 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 ...

Friendship stability in adolescence is associated with ventral striatum responses to vicarious rewards [PDF]

open access: yesNature 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

Primate ventral striatum maintains neural representations of the value of previously rewarded objects for habitual seeking [PDF]

open access: yesNature Communications, 2021
Ventral striatum is known to be involved in the value update for habit learning. Here, the authors report neural and behavioural correlates for the long-term maintenance of value memory for previously rewarded objects in the ventral striatum of humans ...

Aversive counterconditioning attenuates reward signalling in the ventral striatum [PDF]

open access: yesFrontiers 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.

Dopaminergic signaling to ventral striatum neurons initiates sniffing behavior. [PDF]

open access: yesNat Commun
Sniffing is a motivated behavior displayed by nearly all terrestrial vertebrates. While sniffing is associated with acquiring and processing odors, sniffing is also intertwined with affective and motivated states. The systems which influence the display of sniffing are unclear.

Diurnal rhythms across the human dorsal and ventral striatum. [PDF]

open access: yesProc Natl Acad Sci U S A, 2021
Significance Circadian rhythms are important in nearly all aspects of brain function. We previously identified diurnal rhythms in transcripts in human cortical regions that are impacted in aging and schizophrenia. Here, we identify diurnal rhythms in transcript expression across the human dorsal and ventral striatum in subjects without ...

Increased ventral striatal functional connectivity in patients with schizophrenia during reward anticipation

open access: yesNeuroImage: 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

open access: yesiScience, 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.
