Exemplary VOTS neurons in which diverse GIF-related responses during 0.3 Hz HA rotations and HP translations were observed. The GIFs produced during 0.3 Hz HA rotations and horizontal plane translations are similar in profile. Responses to 0.3 Hz, 10°/s roll (A, B) or left-anterior–right-posterior (LA–RP, C) rotations and to 0.3 Hz 75 cm/s2 IA (A, B) or HP −45° (C) translations are shown for a simple (A) and 2 complex (B, C) VOTS neurons. The peak effective GIF in the horizontal plane, i.e., the vector sum of accelerations along the IA (Acc-X, thick solid lines) and NO (Acc-Y, thick dashed lines) axes recorded by a head-mounted triaxial accelerometer, in roll/LA–RP was 0.092 and 0.076 g in translations. Average neural responses (shaded) are superimposed with sinusoidal fits. For graphing purposes, Y-axis (NO) acceleration records are inverted so that neural responses are aligned with rightward IA and backward NO. Calibration bars in C apply to all graphs.
