Urine weight and EUS EMG data recorded from 5 rats over 8 wk. Weekly averages (±SE) of voiding (A) and EMG properties (B) are shown as a function of time after initial implantation. Urine weight/24 h, cumulative urine weight·200 g body wt−1·24 h−1; urine weight/void, urine weight·void−1·200 g body wt−1; EMG amplitude, average rectified EUS EMG amplitude during a void; bursting power, average power in bursting frequency range (typically 4–10 Hz) during a void expressed as percentage of total power during the same period of time; dominant frequency, average of frequency with highest power in bursting frequency range from all spectra during the void; bursting time, cumulative time during the void in which the bursting power exceeds the power in the bursting frequency range expressed as percentage of total power of amplitude-matched non-voiding epochs by 2 SD.
