Figure 1From: Single-Pulse and Unidirectional Electrical Activation of the Cervical Vagus Nerve Reduces Tumor Necrosis Factor in EndotoxemiaVagus fibers in the motor arc of the inflammatory reflex. Electrical stimulation of the cervical vagus nerve was performed using a cuff-mounted bipolar stimulating electrode. (A) (top) cuff electrode (bottom) pulse waveform. PA: pulse amplitude; PW: pulse width (200 to 250 µs); IPI: interpulse interval (50 µs). (B,C) Evoked potentials were measured at the subdiaphragmatic vagus nerve in rats. Evoked potentials are plotted against (B) time and (C) velocity (n = 4).Back to article page
