Zusammenfassung
Introduction: Studies of brain activity in motor actions typically investigate the production of forces that are either constant or have regular time courses such as sinusoidal force changes. The production of random forces that do not follow a fixed template in time and magnitude has rarely been examined. Such an analysis requires however that subjects are able to produce random force profiles and/or are able to learn such a task. Methods: Three groups of subjects were required to learn the production of random grip force profiles. The definition of random was white noise with a low pass filtering (cut off 2Hz)…
