Fig. 4From: Neurophysiological modeling of bladder afferent activity in the rat overactive bladder modelLinear relationship between afferent activity and bladder pressure. A linear polynomial fit of afferent nerve activity as a function of bladder pressure recorded during the relaxation phase of a voiding contraction in the same rat after saline (upper panel) and acetic acid (lower panel) filling. Dots represent the measured afferent activity and the solid line represents the fitted modelBack to article page
