This study investigates how dopamine modulates striatal activity during working memory output-gating using fMRI and finds that sulpiride alters striatal activity and reduces neural stimulus selectivity in visual cortex, affecting task performance.

The paper replicates a previous finding that cognitive effort is influenced by reward rate but shows that recent performance history better explains effort allocation, suggesting a reinterpretation of prior results.

This study investigates the effects of brain stimulation on sustained attention but finds no significant reduction in the vigilance decrement using tDCS or theta tACS.

This study compares univariate and multivariate decoding in the frontoparietal network using group vs. individual ROIs, finding increased univariate activation but no change in discriminability.
