Figure 1.

(A) Time courses of eye-movement displacements obtained following the eye-fixation protocol with cued blinks from one subject. Vertical and horizontal eye movements as measured using the eye-tracking device are shown over 1.5 minutes. The large regular vertical deflections are eye blinks, where the closed eyelids resulted in a loss of tracking. (B) The joined segments of the eye-tracking data after the blinks were removed from one subject. These segments were those derived from the brackets under the traces shown in A. The resolution of eye tracker is 29.6 μm.
