Schematic showing acquisition, transduction and analysis of real-time recorded EMG signaling from an RPNI rat. a. Bipolar collection of raw EMG signals. Ground electrode is referenced in ear. b. Raw EMG signals undergo signal processing in the form of filtering and rectification. c. & d. 300 msec consecutive EMG signal acquisition intervals obtained during c. no observed leg motion (baseline signal activity below threshold), and d. Leg motion and subsequent prosthetic hand activation due to signal surpassing threshold of activation. Blue lines: EMG signal; Red lines: iEMG value; Green lines: Activation threshold
