The paper investigates whether verbal instructions about fear reversal can override memory traces of prior CS-US pairings in brain regions using fMRI and representational similarity analysis.

This study uses fMRI and RSA to show that frontoparietal cortex encodes exemplar-level stimulus information during visual classification, contrary to expectations that such coding would be restricted to posterior regions.

This study uses fMRI to show that frontoparietal brain regions contain both procedural and declarative representations of novel instructions, with procedural activation predicting behavioral performance.

This study uses fMRI and multivariate pattern analysis to show that the ventral pre-supplementary motor area responds similarly to conflict and affect tasks, challenging the idea that these processes are independent.

The paper examines how outcome contingency affects neural coding of rewards and tasks using fMRI, finding enhanced reward coding but no task coding differences under contingency.

The paper uses fMRI and MVPA to test if task representations in frontal and parietal cortex are modulated by task switching, finding no difference in decoding accuracy between switch and repeat trials.
