In medicine and sport science, postural evaluation is an essential part of gait and posture correction. There are various instruments for quantifying the postural system’s efficiency and determining postural stability which are considered state-of-the-art. However, such systems present many limitations related to accessibility, economic cost, size,...

The Bayesian Hurst-Kolmogorov (HK) method estimates the Hurst exponent of a time series more accurately than the age-old detrended fluctuation analysis (DFA), especially when the time series is short. However, this advantage comes at the cost of computation time. The computation time increases exponentially with N, easily exceeding several hours fo...

It is shown that the root mean...

Voluntary movement is driven by the primary motor cortex (M1), and individuals can learn to modulate even single neurons at will. Yet M1 also receives pronounced sensory inputs and contributes to sensory-driven motor responses. To what extent do these non-volitional signals restrict voluntary modulation of M1? Using a task in which the firing rate...
