Figure 2. Example of blinks during fixation in darkness (A, D) and during the presentation of the optic flow pattern (B, E).

In (B) the optic flow is counterclockwise, in (E) clockwise. Dotted lines demarcate the period around the blink-associated artifact of the eye position record, which was not considered for analysis (see Materials and methods). Note the torsional eye position shift towards zero after every blink during the presentation of optic flow stimulus, and less consistently in darkness. (C and F) are comparing the pre- and post-blink torsional eye position for all blinks observed in two blocks examples of subject M.

Figure 2.

Figure 2—figure supplement 1. Torsional eye position before and after blinking for one experimental block per optic flow direction.

Figure 2—figure supplement 1.

The ‘optic flow’ phase I and II, separated by phases of darkness, are demarcated by shaded backgrounds, (A) counterclockwise optic flow, (B) clockwise optic flow. Note the difference in torsional eye position before (red lines) and after blinking (blue lines). The number of spontaneous blinks varied between blocks and subjects. Note the small change in torsional eye position after blinking during darkness phases and the large change during the ‘optic flow’ phases.
