Figure 3

Representative traces of intravesical pressure and the firing rate of the Aδ- and C-fiber in the Sham (upper traces) and BOO rats (lower traces) at day 10. Each square in left panel is corresponding to the right panel. IP: intravesical pressure, FR: firing rate, NA: nerve activity. A: ascending phase, D: descending phase, S: stationary phase. During the measurements, intermittently enhanced SAAs of both Aδ- and C-fiber responses synchronized with bladder microcontractions were frequently observed, especially at the ascending phases, in the BOO rats, but not in the Sham rats.
