Effects of α4β2 nAchRs antagonist DHβE on the cytisine-induced responses. A. Raw recordings showing that cytisine-induced parasympathetic and sympathetic responses (left). Pre-administration of DHβE largely blocked the parasympathetic response with no effect on the sympathetic pressor response (right). B. Mean data showing that, compared with the cytisine alone (open bars), pre-administration of DHβE (solid bars) significantly attenuated the cytisine induced decrease in heart rate (bottom) with no effect on the pressor response (top) or the increase in HR (middle). The vertical dotted lines in the recording traces showed the relative positions of injections. “*” indicate P<0.05 compared with the cytisine only group. n=5
