Maximum activating functions (AFs) evoked along the DNP and CSN by intraurethral stimulation. (A) The maximum AFs evoked along the DNP for intraurethral stimulation 1-7 cm from the urethral meatus. (B) Maximum AFs evoked along the CSN. (C) Maximum AFs evoked at each intraurethral stimulation location for combined DNP and CSN AFs, normalized by dividing by maximum AF over all locations and electrode configurations. (D) Relative stimulation threshold for short, ring, and long electrode configurations. Relative thresholds were determined from the relative values of the inverse of the maximum AFs. (A-C) Maximum AFs were dependent on stimulation location and electrode for the DNP AFs, CSN AFs, and combined DNP and CSN AFs (two-way ANOVA for each, p < 0.0001). (*) indicates significant difference between AFs evoked at different locations (p < 0.05, post-hoc comparison with Bonferroni correction). (C) (†) indicates significant different between AFs evoked with different electrode configurations (p < 0.05, Bonferroni post-hoc comparison).
