Sentence examples for motor variability in from inspiring English sources
The aim of this study was to estimate the between days test retest reliability of nonlinear metrics used to quantify motor variability in a repetitive pipetting task.
An important starting point will be to uncover gene targets or ensembles vital for motor variability in general, and more specifically, phonological and sequence variability related to learned vocalizations.
Probing the neural mechanisms underlying the regulation of motor variability in songbirds.
One interpretation of the data is that PD patients go slower in order to reduce their motor variability in the face of an increased cost for controlling internal noise.
Reviewer #1: In this paper, Santos et al. investigated whether motor variability in the outcome-relevant dimension specifically reduces during learning, and whether such reduction is mediated by neuronal activity in corticostriatal circuits.
It has been postulated that the motor system can learn complex movements by optimizing motor variability in task-relevant dimensions, correcting only deviations that interfere with the final output of the action (Todorov and Jordan, 2002; Scott, 2004; Valero-Cuevas et al., 2009; Diedrichsen et al., 2010).
Intriguingly, the reorganization of HVC-RA synapses we observed experimentally was sufficient to explain the developmental decrease in motor variability seen in vivo (Ölveczky et al., 2011).
The reduction of motor variability specifically in relevant domains suggests that the neural activity giving rise to the task-relevant output is selected during learning.
Across healthy participants, those who had the greatest increase in velocity also had the greatest decrease in motor variability, indicating stronger motivational effects (r = 0.23, p = 0.001; Figure S4A).
How rendition-to-rendition variability in LMAN firing is regulated, and whether it contributes to learning-related changes in motor variability, remains to be explored.
Kinematic motor variability is extensively studied in occupational, clinical and sports biomechanics, but the consistency of most motor variability metrics have never been reported.
