Basically, we delivered #TMS over M1 while participants were performing a visuomotor task involving isometric force production and assessed #corticospinal excitability modulation time-locked to task-instructed force modulation, as well as to #submovements and #tremor in the motor output.
Surprisingly, unlike motor output oscillations, which decrease in amplitude as their frequency increases, corresponding changes in corticospinal excitability maintain a similar magnitude across different timescales.
We suggest this may reflect a non-linear mapping between corticospinal excitability and multiscale movement oscillations, potentially linked to the hierarchical organization of descending motor pathways.
