Beta-band oscillations have been suggested to promote the maintenance of current motor (or cognitive) set, thus signaling 'status quo' system. While this hypothesis has reliably demonstrated in many studies, it fails explain changes beta-band activity due accumulation physical fatigue. In study, we aimed reconcile functional role beta during fatigue within status quo theory. Using an innovative electroencephalography design, identified two distinct power dynamics areas as rises: (i) enhancement at rest, supposedly promoting resting state, and (ii) a decrease contraction, thought reflect increase cortex activation necessary cope with muscular We then conducted effective connectivity analyses, which revealed that modulations contractions were driven by frontal areas. Finally, implemented biologically plausible model replicate characterize our results mechanistically. Together, findings anchor paradigm theory, shedding light on further discuss unified interpretation might conflicting evidence previously encountered literature.
