Interactions of medial and lateral prefrontal cortex in hierarchical predictive coding

The paper extends a computational model of medial and lateral prefrontal cortex interaction to incorporate real-time dynamics and demonstrates its ability to capture neurophysiological and behavioral effects.

Conjunction or co-activation? A multi-level MVPA approach to task set representations

This study uses multi-level MVPA with fMRI to investigate how task sets are represented in the brain, finding co-activation in prefrontal cortex and conjunctive representation in visual cortex.

Testing competing models of dorsal anterior cingulate

The paper tests three theoretical models of dorsal anterior cingulate cortex using a value-based decision-making task and finds the Predicted Response-Outcome model best explains the results.

Predicting motivation: computational models of PFC can explain neural coding of motivation and effort-based decision-making in health and disease

This paper applies computational models of prediction and error to explain neural coding of motivation and effort-based decision-making in prefrontal cortex across health and disease.
