Nerve activity and bladder pressure development during a typical rat voiding cycle. This figure shows a part of a bladder filling cycle. The upper panel shows the pressure during the filling phase with voiding (t1 − t2), marked by high frequency oscillations (HFO) of the urethral sphincter. At pthres the pressure rises above the baseline and increases rapidly until a voiding occurs. pmax represents the maximum pressure just before the start of urine flow. The lower panel shows the corresponding afferent nerve activity
