Spinal cord injury figure 1

The method that was used involved intracortical brain-computer interfaces (iBCIs) implanted into the brain, which consisted of just under 200 microelectrodes connected to a neural decoder. This system translated the firing of action potentials and their frequency power into commands that were sent to the FES system. The functional electrical stimulation (FES) had electrodes under the skin on the muscle of the patient that would stimulate contraction when signaled. In this experiment, a mobile arm support was used against gravity and for abduction and adduction movements. Fig. 1A shows these systems attached to the patient. In fig. 1B, graphs are shown demonstrating the neural patterns recognized for different movements involving the extension and flexion.
