Abstract
The nervous system is highly adaptive to cope with changes. But the natural neural adaptation
is often not optimal. If we interface and communicate with the nervous system, we might
able to guide the neural adaptation to the proper direction. Electrical circuits and systems can
favorably intervene the nervous system operation, as the neural signal can be recorded and
modulated by electrical stimulation (E-stim). The closed-loop E-stim has been applied in
multiple ways to modulate ascending sensory feedback or descending motor commands. In
this talk, I will introduce one approach of this closed-loop E-stim, applied onto distal
cutaneous nerves. The closed-loop E-stim not only augments sensory feedback but also
modulates motor output in a desired way. I will also share multiple human and animal
experimental data to show the efficacy of the closed-loop E-stim.
