Striatal action-value neurons reconsidered
eLife, 2018 It is generally believed that during economic decisions, striatal neurons represent the values associated with different actions. This hypothesis is based on studies, in which the activity of striatal neurons was measured while the subject was learning ...

Simulating Effects of Learning and Lesions with a Model of Intrinsic and Synaptically Gated Responses of Striatal Cholinergic Interneurons [PDF]
, 2006 The giant cholinergic interneurons of the striatum are tonically active neurons (TANs) that respond with characteristic pauses to novel events and to appetitive and aversive conditioned stimuli.

Basal ganglia role in learning rewarded actions and executing previously learned choices: Healthy and diseased states [PDF]
, 2020 The basal ganglia (BG) is a collection of nuclei located deep beneath the cerebral cortex that is involved in learning and selection of rewarded actions. Here, we analyzed BG mechanisms that enable these functions.

eLife, 2016 Several lines of evidence suggest that the striatum has an important role in spatial working memory. The neural dynamics in the striatum have been described in tasks with short delay periods (1–4 s), but remain largely uncharacterized for tasks with ...

3D Brain Vascular Niche Model Captures Glioblastoma Infiltration, Dormancy, and Gene Signatures
Advanced Science, EarlyView.This study developed a 3D brain vascular niche model that capture the key features of glioblastoma including perivascular infiltration, gene signature, dormancy and chemo resistance, by comparing 3D model with in vivo condition using identical glioma stem cells.

Encoding of Marginal Utility across Time in the Human Brain [PDF]
, 2009 Marginal utility theory prescribes the relationship between the objective property of the magnitude of rewards and their subjective value. Despite its pervasive influence, however, there is remarkably little direct empirical evidence for such a theory of

Weight Cycling Deregulates Eating Behavior in Mice via the Induction of Durable Gut Dysbiosis
Advanced Science, EarlyView.Weight cycling in Humans is suspected to dysregulate eating behavior. Mice submitted to body weight cycling by alternating western‐type and regular chow diets display increased hedonic appetite when exposed to a palatable diet, reminiscent of binge‐eating episodes.

Synapse-specific opioid modulation of thalamo-cortico-striatal circuits
eLife, 2019 The medial thalamus (MThal), anterior cingulate cortex (ACC) and striatum play important roles in affective-motivational pain processing and reward learning. Opioids affect both pain and reward through uncharacterized modulation of this circuitry.

Gain Modulation by Corticostriatal and Thalamostriatal Input Signals during Reward-Conditioned Behavior. [PDF]
, 2019 The cortex and thalamus send excitatory projections to the striatum, but little is known about how these inputs, either individually or collectively, regulate striatal dynamics during behavior.
