Cardiovascular effects of different doses of gabapentin microinjected into the NTS in rats. (A) Representative tracings demonstrating the cardiovascular effects of different doses (3.3-33 nmol/60 nL) of gabapentin in anesthetized rats. (B) Effects of unilateral NTS microinjection of gabapentin on MBP and HR. BP, blood pressure; MBP, mean blood pressure; HR, heart rate recorded at paper speed of 3 mm/min. Horizontal bar represents recording during 5-min intervals. * p < 0.05 vs. vehicle group, n = 3.
