Motor Control: No Constant but Change

Motor Control: No Constant but Change

We rely on predictions to rapidly select our walking gaits. New research suggests that the formation of these predictions is driven by the difference between the walk we expect and the walk we get.

Motor control: Forcing neurons to change

New research shows that the properties of cells in motor cortex change during learning of new tasks, shedding new light on the neural basis of motor adaptation.

Cerebellum activation associated with performance change but not motor learning.

The issue of whether the cerebellum contributes to motor skill learning is controversial, principally because of the difficulty of separating the effects of motor learning from changes in performance. We performed a functional magnetic resonance imaging investigation during an implicit, motor sequence-learning task that was designed to separate these two processes. During the sequence-encoding ...

Motor unit control properties in constant-force isometric contractions.

1. The purpose of this study was 1) to characterize the decrease observed in mean firing rates of motor units in the first 8-15 s of isometric constant-force contractions and 2) to investigate possible mechanisms that could account for the ability to maintain force output in the presence of decreasing motor unit firing rates. 2. The decrease in mean firing rates was characterized by investigati...

Change is inevitable--change is constant.
