This study uses MEG to show that human motor areas exhibit RPE-like signals during deterministic tasks, supporting embodied decision-making.

The paper investigates premotor cortex activity during passive observation of rule-based stimuli, finding activation related to abstract rule evaluation even without motor actions.

The paper shows that decision-related activity in macaque PMd is linked to action selection, not perceptual processing, when specific stimulus-response associations are known.
