Relations between left-right pupil size difference in different conditions.

<p>Dots and open squares represent the left-right pupil size differences recorded in NO CONTACT and CROWN ON condition respectively, plotted as a function on the corresponding values obtained in the CROWN OFF condition. A. Basal pupil size asymmetry. B. Task pupil size asymmetry. Dotted lines are the regression lines obtained for dots and open square data, which correspond to the following equations: A. dots: r = 0.941, P<0.0005, Y = 0.468X + 0.18; squares: r = 0.958, P< 0.005, Y = 0.167X + 0.001. B. dots: r = 0.945, P<0.0005, Y = 0.666X–0.027; squares: r = 0.8878, P< 0.001, Y = 0.345X–0.036.
