Dopamine promotes instrumental motivation, but reduces reward-related vigour

open access: yeseLife, 2020
We can be motivated when reward depends on performance, or merely by the prospect of a guaranteed reward. Performance-dependent (contingent) reward is instrumental, relying on an internal action-outcome model, whereas motivation by guaranteed reward may ...

Opposite initialization to novel cues in dopamine signaling in ventral and posterior striatum in mice

open access: yeseLife, 2017
Dopamine neurons are thought to encode novelty in addition to reward prediction error (the discrepancy between actual and predicted values). In this study, we compared dopamine activity across the striatum using fiber fluorometry in mice.

Neural Correlates of Rewarded Response Inhibition in Youth at Risk for Problematic Alcohol Use

open access: yesFrontiers in Behavioral Neuroscience, 2017
Risk for substance use disorder (SUD) is associated with poor response inhibition and heightened reward sensitivity. During adolescence, incentives improve performance on response inhibition tasks and increase recruitment of cortical control areas (Geier

Genetic Relationships Between Ethanol-Induced Conditioned Place Aversion and Other Ethanol Phenotypes in 15 Inbred Mouse Strains

open access: yesBrain Sciences, 2019
The genetic relationships between different behaviors used to index the aversive effects of ethanol are unknown. To address this issue, ethanol-induced conditioned place aversion (CPA) was tested in a genetically diverse panel of 15 inbred mouse strains.
