Notes: All parameters are not significantly different between prestimulation and each measurement point. The data are the means ± standard deviations.
Abbreviations: MBP, mean blood pressure; OPP, ocular perfusion pressure; PR, pulse rate. TES and sham stimulation group have six and four subjects, respectively. Statistical analyses were performed by two-way repeated measures ANOVA with post hoc test, unpaired Student t-tests.
