Multifractal Dynamics in Executive Control When Adapting to Concurrent Motor Tasks

open access: yesFrontiers in Physiology, 2021
There is some evidence that an improved understanding of executive control in the human movement system could be gained from explorations based on scale-free, fractal analysis of cyclic motor time series. Such analyses capture non-linear fractal dynamics
