From: Measuring and modeling the effects of vagus nerve stimulation on heart rate and laryngeal muscles
Vagotomy (VNX) distal to the stimulation cuff abolished VNS-evoked responses. A-B Example heart rate (HR) and EMG responses. Stimulation was applied at 20 Hz at bradycardia threshold (BCT) determined pre-VNX from t = 10 s to t = 40 s (red bar). A HRnorm pre-VNX (black) and post-VNX (purple). B EMGnorm pre-VNX (black) and post-VNX (purple). C EMG response to a single stimulation pulse pre- and post-VNX. D HRnorm pre- and post-VNX. E EMGnorm pre- and post-VNX. *** p < 0.0001, n = 10
