Closed-loop control improved facial prosthesis actuation in reinforced DEAs
—
in EngineeringWhat the study found A model-based closed-loop controller for reinforced dielectric elastomer actuators was able to improve actuation performance for a facial prosthesis. The designed prosthesis showed a root mean square error of 2.06% in response to electromyography signals from the zygomaticus major muscle, which is responsible for smiling. Why the authors say this matters…
Brief electrical stimulation induced ketamine-like plasticity in human neurons
—
in NeuroscienceBrief electrical stimulation produces ketamine-like structural plasticity in human dopamine neurons via calcium-dependent BDNF and mTOR signaling, reversing cortisol-induced damage.
