Abstract
Motor units (MUs) receive a common synaptic input that contains oscillations, especially in the beta band (13-30 Hz). These oscillations have a cortical origin, but their purpose is unclear as frequencies above 10 Hz do not translate into a force output. I will present results from our study showing that these oscillations are modulated by mental tasks that are unrelated to the actual motor task. This supports the hypothesis that these oscillations may, at least in part, leak from the brain downstream to MUs without any particular purpose (i.e., they are leftovers). This finding may provide a novel control channel for movement augmentation based on high-density EMG, and I will also present results on the feasibility of this application perspective.
