Granger causality mapping during joint actions reveals evidence for forward models that could overcome sensory-motor delays.

Studies investigating joint actions have suggested a central role for the putative mirror neuron system (pMNS) because of the close link between perception and action provided by these brain regions [1], [2], [3]. In contrast, our previous functional magnetic resonance imaging (fMRI) experiment demo...
