A and B. Diagram showing parameters of bladder activity measured during cystometrograms in two conscious chronic spinal cord injured cats. a, Bladder capacity (BC), the volume infused intravesically to induce a micturition reflex contraction that was identified by coincident reflex contractions of the hind legs. b, Maximal micturition pressure (MMP). c, Pre-micturition contraction (PMC) frequency or area under curve (PMC-AUC) measured for a period of 200 s. prior to the micturition reflex contraction. Down arrow indicates start of intravesical infusion. Up arrow indicates end of intravesical infusion. * denotes the first micturition reflex contraction. A. Tracing shows a large difference between the amplitude of PMCs and the first micturition reflex contraction. A second micturition contraction occurred after the end of intravesical infusion. B. Tracing from another experiment shows that the largest amplitude PMCs can be similar in amplitude to that of the first micturition reflex contraction. Both tracings show PMCs gradually increase in amplitude during intravesical infusion.
