Both conditions showed activation in the dorsal and parietal premotor areas. However, the voluntary condition also showed activation in the right dorsolateral prefrontal cortex, which did not appear in the reflexive condition. As this area has been shown to be associated with working memory, it may indicate that working memory is engaged voluntarily.
Activation was observed in dorsal and parietal premotor areas for both conditions. Nevertheless, the voluntary condition exhibited activation in the right dorsolateral prefrontal cortex, which was not present in the reflexive condition. This area has been associated with working memory, indicating that it might be engaged during voluntary actions.
