Comparisons of average responses of simple VOTS neurons to 2 classes of otolith afferents across frequency. The frequency-dependent sensitivity and phase of low-pass neurons (A) and flat-gain neurons (B) are adequately modeled with a fractional leaky integrator, in the form of k_s*(1 + τ_ps)^h, −1 < h < 0, with very regular (H_VR, h ≅ −0.3) or irregular (H_IR, h ≅ −0.7) afferent inputs at test frequencies. Afferent responses were obtained from previously published data in squirrel monkeys (Goldberg et al. 1990).
