Synchronization of motor-unit firings in several human muscles.
1. Synchronization of concurrently active motor-unit firings was studied in six human muscles performing isometric constant-force contractions at 30% of the maximal level. The myoelectric signal was detected with a quadrifilar needle electrode and was decomposed into its constituent motor-unit action-potential trains with the Precision Decomposition technique, whose accuracy has been proven pre...
متن کاملLateral Vibrations of Single-Layered Graphene Sheets Using Doublet Mechanics
This paper investigates the lateral vibration of single-layered graphene sheets based on a new theory called doublet mechanics with a length scale parameter. After a brief reviewing of doublet mechanics fundamentals, a sixth order partial differential equation that governs the lateral vibration of single-layered graphene sheets is derived. Using doublet mechanics, the relation between natural f...
متن کاملStatistically 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...
متن کاملSynchronization 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 ...
متن کاملSynchronization of Motor Unit Firings : 1 An Epiphenomenon of Firing Rate Characteristics not Common Inputs
25 Synchronous motor unit firing instances have been attributed to anatomical inputs shared 26 by motoneurons. Yet, there is a lack of empirical evidence confirming the notion that common 27 inputs elicit synchronization under voluntary conditions. We tested this notion by measuring 28 synchronization between motor unit action potential trains (MUAPTs) as their firing rates 29 progressed from a...
