Figure Lengend Snippet: Transcutaneous cervical vagus nerve stimulation (tcVNS) targets the vagus nerve non-invasively with electrical stimulation; the putative mechanism of action for resultant cardiorespiratory variations involves tcVNS-induced afferent signaling, followed by efferent modulation. (Right) In this double-blind, sham-controlled study, stimulation is delivered to the left side of the neck, targeting the cervical projection of the vagus nerve. The electrocardiogram (ECG) and respiratory effort (RSP) are sensed at the locations depicted.

Article Snippet: B. Physiological Sensing Respiratory effort (RSP) and electrocardiogram (ECG) signals were measured at the locations shown in (right) from subjects in a supine position using the Biopac RSPEC-R (Biopac Systems, Goleta, CA, USA).

Figure Lengend Snippet: Fig. 7. (a) The interval between the R-wave of the electrocardiogram and the arrival of the W1 wave, and (b) the interval between the arrival of the W1 and W2 waves, determined by the non-invasive diameter-velocity method. Left hand plots show the mean (solid line) § SD (dashed lines) for n = 9 rabbits; esmolol was administered at increasing doses immedi- ately after the readings at 0, 10 and 20 min. The average interval throughout the 30-min period in the same rabbit was subtracted from each reading. The right-hand plots provide individual data for two rabbits (RNLX, RNNE) administered vehicle only. Asterisks indicate significance: **p < 0.01; ***p < 0.005.
