Encoding of Action History in the Rat Ventral Striatum [PDF]

Journal of Neurophysiology, 2007
In a dynamic environment, animals need to update information about the rewards expected from their alternative actions continually to make optimal choices for its survival. Because the reward resulting from a given action can be substantially delayed, the process of linking a reward to its causative action would be facilitated by memory signals ...

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.

Self-Affirmation Activates the Ventral Striatum [PDF]

, 2016
Self-affirmation (reflecting on important personal values) has been shown to have a range of positive effects; however, the neural basis of self-affirmation is not known. Building on studies showing that thinking about self-preferences activates neural reward pathways, we hypothesized that self-affirmation would activate brain reward circuitry during ...

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 ...

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

Nature 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 ...

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 ...

Contextual novelty changes reward representations in the striatum [PDF]

, 2010
Reward representation in ventral striatum is boosted by perceptual novelty, although the mechanism of this effect remains elusive. Animal studies indicate a functional loop (Lisman and Grace, 2005) that includes hippocampus, ventral striatum, and ...

Ventral Striatum and the Evaluation of Memory Retrieval Strategies [PDF]

Journal of Cognitive Neuroscience, 2014
AbstractAdaptive memory retrieval requires mechanisms of cognitive control that facilitate the recovery of goal-relevant information. Frontoparietal systems are known to support control of memory retrieval. However, the mechanisms by which the brain acquires, evaluates, and adapts retrieval strategies remain unknown.

An open cortico-basal ganglia loop allows limbic control over motor output via the nigrothalamic pathway

eLife, 2019
Cortico-basal ganglia-thalamocortical loops are largely conceived as parallel circuits that process limbic, associative, and sensorimotor information separately. Whether and how these functionally distinct loops interact remains unclear.
