(a) Blood pressure, (b) heart rate and (c) nerve firing frequency before (filled bars) and after (clear bars) administration of different doses of apomorphine (APO) in the CNS intact males and females and male rats with a midthoracic spinal transection. Mean values were calculated for 1 min before and for a similar period commencing at 20 s after apomoprhine. Statistical comparisons before and after were made using the paired t-test. ^*indicates P<0.05; ^**indicates P<0.01; ^***indicates P<0.001.
