Mean MSNA bursts per minute. The paired (RM one-way ANOVA, P = 0.6080; n = 9) and unpaired (ordinary one-way ANOVA, P = 0.1022; n = 17 for sinusoidal galvanic vestibular stimulation (sGVS); n = 22 for transcranial alternating current stimulation (tACS) of the dorsolateral prefrontal cortex (dlPFC); n = 11 for combined stimulation) mean MSNA bursts per minute data (calculated from the root mean square (RMS) of the raw nerve activity) from three-minute time periods before, at the start, and at the end of each stimulation protocol is displayed. For both the paired and unpaired data, no statistically significant differences (P > 0.05) were found between any stimulation conditions. ‘Combo’ refers to combined sGVS and tACS stimulation. Data are presented as mean ± standard deviation (SD)
