Abstract:In the absence of disease, humans produce smooth and accurate movement trajectories. Despite such ‘macroscopic’ aspect, the ‘microscopic’ structure of movements reveals recurrent (quasi‐rhythmic) discontinuities. To date, it is unclear how the sensorimotor system contributes to the macroscopic and microscopic architecture of movement. Here, we investigated how corticospinal excitability changes in relation to microscopic fluctuations that are naturally embedded within larger macroscopic variations in motor out… Show more
