The investigational set-up as applied in the study. For the purpose of the present study, the MR-compatible robot MARCOS was mounted on the bench of the MR-scanner. The robot was used to measure and control the delivery of active and passive stepping movements (a). During task execution, the word “MOVE” was presented on the screen and participants conducted stepping movements in the rhythm of the concurrently presented auditory stimulus (metronome). This was followed by the acquisition of the BOLD-signal, while participants fixated on a white cross on the screen. Subsequently, the word “LISTEN” and the metronome were presented concurrently, again followed by the acquisition of the BOLD-signal (b)
