Mean responses with superimposed SE of renal sympathetic nerve activity (rSNA) with arterial pressure at the level of the brain (brain AP) of eight rats with anti-G equipment exposed to +5.0 Gz acceleration for 15 s. rSNA was expressed by % of resting activity during the control period. **p < 0.01 by one-factor ANOVA with the Tukey–Kramer test. rSNA increased at both of the acceleration and deceleration hypotensions. Increase in rSNA at the deceleration hypotension was significantly greater than that at the acceleration hypotension [17, 18, 22]. The data does not support the opinion that the deceleration hypotension may be caused by smaller responses in sympathetic activity
