Change in DBP during ganglionic blockade and T50, error signal, sensitivity slope and baseline MSNA for young and older women

Variables	Young Women (n=12)	Older Women (n=12)
Change in DBP after autonomic blockade, mmHg	−5 ± 6 (−16–4)	−19 ± 6* (−31–−9)
T50, mmHg	66 ± 1 (57–75)	74 ± 2* (62–87)
Error signal (T50-DBP), mmHg	−8 ± 1 (−17–−3)	2 ± 1* (−5–10)
Sensitivity slope (bursts/100hb·mmHg)	−1.12 ± 0.28 (−3.53–0.02)	−0.87 ± 0.16 (−1.98–−0.09)
MSNA burst frequency, bursts/min	15 ± 1 (8–23)	33 ± 3* (14–46)
MSNA burst incidence, bursts/100 hb	25 ± 2 (10–36)	57 ± 5* (29–80)

Data are presented as mean±SEM (minimum-maximum). DBP, diastolic blood pressure; hb, heartbeats; MSNA, muscle sympathetic nerve activity.
