This study uses high-resolution fMRI to show that SN/VTA and LC activity differ in their response to rewarded versus visually salient stimuli, indicating distinct roles in reward and salience processing.

This study uses fMRI to investigate how the locus coeruleus and SN/VTA contribute to reward and valence processing in humans, finding distinct and joint roles in response to reward and negative valence.

The paper reanalyzes a dataset using multivariate pattern analysis to identify brain regions involved in maintaining temporal and contextual information during action sequence execution.

This paper proposes a framework connecting motivational and cognitive impairments in depression using computational models of cognitive control.
