Fluorescent images of medulla samples from multiple cuffing variations of rats. (a) Cuffs placed adjacent to left vagus nerve, but not enclosing it (eRx110), produced bright efferent fiber FG transport illumination on both left and right sides of DMN. (b) Cuffed with standard record and stimulation cuffs by visiting surgeon (eRx116), showing bright FG illumination on the right side of the DNM from uncuffed right vagus nerve, but limited efferent transport from the left vagus on the left side of the DMN. (c)–(f) All rat medulla samples showed near-complete suppression of efferent transport on the left side. (c) Cuffed with single industry-made (CorTec; Freiburg, Germany) tunnel electrode with 0.6 mm inner diameter (eRx118). (d) Cuffed with a single standard stimulation cuff (eRx113). (e) Cuffed with sham record and stimulation cuffs containing no metal electrodes (eRx132). (f) Cuffed with standard record and stimulation cuffs, but not stimulated (eRx75). Scale bars = 250 microns.
