Characteristics of gaze shifts (GS) during the four locomotor tasks. A–E: Gaze shifts moving gaze/surface intersect point further away from the cat. F–J: Gaze shifts moving gaze/surface intersect point toward the cat. Data obtained from individual cats are color-coded as indicated at the bottom of the figure; data are shown as mean ± SEM. A, F: Distance ahead of the cat, at which the gaze shifts were initiated. B, G: Time needed for the cat to reach the gaze shift initiation point. C, H: Number of steps required from the cat to reach the gaze shift initiation point; calculated by dividing the mean needed time by the mean step duration. D, I: Duration of the gaze shift. E, J: Amplitude of a gaze shift showing how far along the surface the gaze moved during the shift.
