Figure Lengend Snippet: LMEP recording. Recording electrodes were subcutaneously placed in proximity to the left laryngeal muscles, to record the LMEP (A), and the axillar region, to record non‐laryngeal muscular activity (B), and both were referenced to the ground electrode placed subcutaneously in the sole of the right foot (C). VNS pulses were administered via the DS4 constant current stimulator (D), via stimulation cables connected the connector pins of the VNS electrode in the headcap. The recorded EPs were amplified and filtered via a pre‐amplifier (E) and amplifier (F), and digitized by a NIDAQ (G) for storage in a local computer. (H) shows an example of an LMEP recording with the latency to the initial negative peak labeled as (I).
