Statistically rigorous calculations do not support common input and long-term synchronization of motor-unit firings

Statistically rigorous calculations do not support common input and long-term synchronization of motor-unit firings.

Over the past four decades, various methods have been implemented to measure synchronization of motor-unit firings. In this work, we provide evidence that prior reports of the existence of universal common inputs to all motoneurons and the presence of long-term synchronization are misleading, because they did not use sufficiently rigorous statistical tests to detect synchronization. We develope...

Statistically rigorous calculations do not support Common Input 1 and Long - Term synchronization of motor unit firings

23 Over the past four decades, various methods have been implemented to measure 24 synchronization of motor unit firings. In this work we provide evidence that prior reports of the 25 existence of universal common inputs to all motoneurons and the presence of long-term 26 synchronization are misleading because they did not use sufficiently rigorous statistical tests to 27 detect synchronization...

Synchronization of motor unit firings: an epiphenomenon of firing rate characteristics not common inputs.

Synchronous motor unit firing instances have been attributed to anatomical inputs shared by motoneurons. Yet, there is a lack of empirical evidence confirming the notion that common inputs elicit synchronization under voluntary conditions. We tested this notion by measuring synchronization between motor unit action potential trains (MUAPTs) as their firing rates progressed within a contraction ...
