A number of studies have demonstrated that BCI had a potential to improve the performance by learning. Here, we developed the system of recurrent BCIs that creates an artificial neural connection (ANC) between muscle and peripheral nerve that can boost the muscle activity. The ANC can detect the firing pattern of motor units and converted in real-time to activity-contingent electrical stimuli delivered to the peripheral nerve. Just after performing ANC, the wrist trajectory overshot the target. As the practice progressed with ANC, the wrist trajectories hit the target. These results indicate that the subjects could adapt to the novel ANC that boosts the on-going muscle activities.
