Demonstration of hysteresis in two example units. a i Bladder pressure trace with periods corresponding to bladder contractions highlighted (different colors and different symbols) and volume infused (black dotted line). Open symbols are used to indicate contractions during 25–50 % leak volume and closed symbols are used to indicate contractions during 50–75 % leak volume. ii Firing rate for a bladder unit that correlates well with pressure during the same time period (symbols correspond to those used in i, with correlation coefficient (ρ) indicated). iii Firing rate for a bladder unit that is weakly correlated with bladder pressure. b Waveform and interspike interval (isi) histogram, with bin width = 5 ms, for neurons in a. c Bladder pressure plotted against firing rate of respective neurons from a for each contraction during the designated periods at 25–50 % leak volume (left column) and 50–75 % leak volume (right column). The Hmax and Hmean values are given above the plots. Arrows represent direction of cycle
