This paper models working memory as a feedback-control system, showing that increased memory load requires more sustained prefrontal control and that routing strategies affect mnemonic efficiency and robustness.

This study investigates how the dorsomedial prefrontal cortex links abstract planning to motor execution using functional MRI in humans.

The paper investigates how neural task representations adapt to task uncertainty using fMRI, finding dissociable modulations of conjunctive and compositional representations in the frontoparietal network.

The paper compares hierarchical and flat neural network models to understand cognitive control in the frontal medial cortex using fMRI data.

The paper investigates theta phase resetting in the human parahippocampal gyrus during navigation, finding it correlates with BOLD activation in specific PHG clusters.

The paper shows that damage to caudal anterior cingulate cortex (ACC) reduces reward positivity (RewP) amplitude, confirming its role as the neural generator of this ERP component in humans.

The paper investigates whether the successor representation supports hierarchical abstraction for goal-directed behavior by analyzing human choices in a virtual museum task.

The paper investigates how average task value influences reward-related ACC activity, finding that reward positivity is reduced in high-value tasks independent of reward magnitude or outcome expectancy.

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

The paper examines alpha event-related desynchronization during reward processing in schizophrenia, finding altered alpha ERD magnitude between reward outcomes and associations with trait rumination.

This study uses EEG to examine reward anticipation and outcome processing during slot machine play, finding distinct neural responses to winning, near misses, and total misses.

The paper examines reward processing in schizophrenia using ERPs, finding altered later reward outcome evaluation in early-stage patients and a link between brain age and depressive symptoms.

This study investigates the neural correlates of transition model learning through EEG experiments, identifying fronto-midline theta and delta oscillations and the anterior midcingulate cortex's role in planning behavior.

This study investigates prediction error signals in medial prefrontal cortex (mPFC) during goal and subgoal tasks, showing mPFC signals subgoal-related errors independently and context-dependent goal-related errors.

The paper investigates how cognitive effort and reward valuation change during a prolonged task using electrophysiological measures from the anterior cingulate cortex.

The paper proposes a theoretical framework where each long-term memory system functions as a cognitive map, addressing limitations of traditional hippocampus-based cognitive map theories.
