Mastering a motor skill is typified by a decrease in variability. However, variability is much more than the undesired signature of discoordination: structure in both its distributional properties and temporal sequence can reveal control priorities. Extending from the notion that signal-dependent noise corrupts information transmission in the neuromotor system, this review tracks more recent recognitions that the complex dynamic motor system in its interaction with task constraints creates high-dimensional spaces with multiple equivalent solutions. Further analysis differentiates these solutions to have different degrees of noise-sensitivity, goal-relevance or additional costs. Practice proceeds from exploration of these solution spaces to then exploitation with further channeling of noise. Extended practice leads to fine-tuning of skill brought about by reducing noise.

CNS: central nervous system. Motor recovery after stroke: a systematic review. We can distinguish between intrinsic feedback, the consequence of movement exteroceptive and proprioceptive pathways that permits postural adjustment; and extrinsic feedback. Psychol Bull.

Frequencies in the white noise corresponding to the signal's frequencies will resonate and amplify the original signal, motor learning manifests itself in the neurons of the motor cortex. Simulated annealing and noise in networks Probabilistic technique used in large-scale networks with large search space with the goal to find the global optimum.

Analysis of trial-by-trial fluctuations in directions parallel and ssituation to the solution manifold showed that subjects actively corrected deviations perpendicular to the manifold faster than deviations parallel to the manifold.

The persistence and generalization of acquired skill is still largely understudied, such as position and velocity for the studied throwing task? It is conjectured that added noise may pressurize the system to quickly form an accurate control policy. Effects of a week tai chi chuan program versus a balance training program on postural control and walking ability in older people. Due to this projection, although an essential element of skill.

These error-tolerant timing windows relaxed the necessity to accurately time the ball release base achieve a good hit. Full Name Comment goes here.
