Illustrative traces of compound action potential and its conductibility parameters for control and diabetic rats. (a) represents illustrative traces of compound action potential (CAP) for control (left), near-normoglycemic (center), and hyperglycemic (right) groups. Inset shows amplitude and time scale bar. (b) shows conduction velocity of 1st and 2nd CAP components for control (), near-normoglycemic () and hyperglycemic () groups and (c) shows the amplitude of CAP components. (d) shows CAP duration in 50% of CAP peak amplitude for control (), near-normoglycemic (), and hyperglycemic (). In (b), (c), and (d) black and grey bars represent 1st and 2nd components, respectively. The * symbol indicates statistical difference related to control (, ANOVA followed by Holm-Sidak comparisons test for data in (b) and (c) and , Student’s -test for (d)).
