Fixational saccade inhibition and pupil dilation during self-paced limb movement preparation.

Note that, in spite of this highly significant evidence for an association when aggregating across participants, the regression coefficient for event-related pupil size modulation did show substantial variability among participants (for hand and foot, respectively, the median coefficients were 0.077 and 0.079, the inter-quartile ranges were 0.28 and 0.26, and the proportions of participants with a value greater than 0 were 0.66 and 0.72).
