Descending and ascending pathways of GPDC between BA6 cluster and left leg muscles for different pedaling protocols in healthy subjects, average across ICs in the selected pedaling protocol in Table 2, half error-bar= ± 1SEM. Different color represents different muscle. Upper: brain to muscle connectivity, descending pathway, lower: muscle to brain connectivity, ascending pathway. **, p<0.01, *, p<0.05 for group level (all muscles) comparison between pedaling protocols, ##, p<0.01, #, p<0.05 for individual muscle comparison with passive pedaling
