Six-transistor amplifier having high-impedance differential input for commercial eeg or emg electrodes and gain of 10,000 from 5 to 10,000 cps drives modulator Q4-Q5 from decoupling transformer. Modulator makes stimulator (astable mvbr Q6-Q7) apply pulsating voltages to muscles of hand, to make hand open in response to signals picked up by electrodes ovel shoulder muscles, thereby bridging severed arm nerves．－L Vodovnik and W. D. McLeod, Electronic Detours of Broken Nerve paths,Electronics,38:19,p110-116.
