Fig. 8 — Detection thresholds for regular and irregular canal and otolith afferents during 1 Hz sinusoidal GVS. a, b Firing rate plotted as a function of stimulus current for regular (blue) and irregular (red) canal and otolith afferents. c, d Signal detection theory was used to compare the distribution of firing rates for a given value of stimulus current and that obtained for zero current (see insets in a, b) to obtain a plot of d′ as a function of stimulus current. The detection threshold T_d´ was computed as the lowest absolute value of stimulus current for which d’ = 1 (dashed horizontal gray lines). e, f Population-averaged detection threshold values T_d´ for regular (blue) and irregular (red) canal and otolith afferents as a function of frequency. Neuronal detection thresholds varied with GVS frequency for all afferent types (linear mixed model: p < 0.001), but remained relatively unchanged across firing rate regularity and end organ innervation (Student t-tests: p > 0.00625 Bonferroni’s correction for multiple comparisons).
