Characterization and Mitigation of Bias in Parametric Mapping of Reward-Induced Dopamine Release using Simultaneous Positron Emission Tomography and Magnetic Resonance Imaging
(2020-09-25)The dopamine system plays an essential role in learning associated with reward expectation and receipt. [11C]Raclopride positron emission tomography (PET) can be used to observe dopamine D2/D3 receptor binding and its ... -
Diverse physiology and function of dopaminergic neurons in behaving Drosophila
(2021-05-14)In many animals, including both mammals and insects like Drosophila, dopamine is associated with learning, motivation, and regulation of voluntary movement. In mammals, the activity of individual dopaminergic neurons (DANs) ... -
Dopamine in the tail of striatum regulates post-assessment avoidance of stimulus novelty
(2021-11-16)Novelty drives animals’ active sampling of their environment and influences learning. Novel objects evoke characteristic behavioral responses such as approach, retreat, and avoidance of these objects, but how the complex ... -
Imaging the pathophysiology of major depressive disorder - from localist models to circuit-based analysis
(BioMed Central, 2014)The neuroimaging literature of Major Depressive Disorder (MDD) has grown substantially over the last several decades, facilitating great advances in the identification of specific brain regions, neurotransmitter systems ... -
Mechanisms of motivation–cognition interaction: challenges and opportunities
(Springer Science + Business Media, 2014)Recent years have seen a rejuvenation of interest in studies of motivation–cognition interactions arising from many different areas of psychology and neuroscience. The present issue of Cognitive, Affective, & Behavioral ... -
Relationship of striatal dopamine to reward history and action during probabilistic decision making
(2023-05-02)Adaptive behavior requires animals to flexibly switch between actions to obtain reward. It is unknown how the brain mediates transitions when the relative value between actions is unclear. To study these processes, we ...
