Null effects of musical groove on cortico-muscular coherence during isometric contraction

Humans have a natural tendency to move music, which has been linked the tight coupling between auditory and motor system active role of in perception musical rhythms. High-groove music is particularly successful at inducing spontaneous movement, due engagement (motor) prediction processes. However, how listening transfers muscles even when no movement intended less known. Here we used cortico-muscular coherence (CMC) investigate changes along pathway response different levels groove without intention move. Electroencephalography (EEG), Electromyography (EMG) from finger foot flexors, continuous force signals were recorded 18 participants while either high-groove low-groove or silence. Participants required hold steady isometric contraction during all conditions. Subjective ratings confirmed that successfully induced. evidence was found for an effect on participants' CMC ability maintain both upper lower limbs irrespective expertise. These results thus do not support top-down influence coupling. Nevertheless, it remains possible such might occur form dynamic modulations and/or with more listening. Therefore, these encourage further research better understand effects system.
