Therefore, we assume that the pupil dilation signature during emotion regulation is informative about the individual cognitive engagement during this self-control process. We chose to investigate the engagement in regulation via pupil dilation because the ability to engage self-control is fundamental for ...
The data of main interest were the pupillary responses. In heterosexual male observers, these responses were consistent with their reported sexual interests. Thus, pictures of women elicited a clear pupillary dilation that was not present during the viewing of men and children. In female observers,...
Pupillometry, the measurement of changes in pupil diameter, is a relatively older method for inferring different types of activity in the brain.Pupil dilationis an autonomic sympathetic nervoussystem responsethat can provide indices of attention, interest, or emotion and is correlated with mental workl...
Pain measurement Pain was measured by subjective grading on a visual analog scale (VAS), immediately following the instillation of pupil dilation drops and gel. The VAS is a horizontal line measuring exactly 10 cm (100 mm), as shown in Figure 1. Each patient was asked to mark a vertical ...
Pupil dilation metrics correlate with individual differences measured by the Social Responsiveness Scale (SRS), a quantitative measure of autism traits. These results suggest that using a novel, yet simple, paradigm can result in meaningful pupil metrics that correlate with individual differences in ...
Is the dilation of the eye from the drops given during an eye exam the same as the dilation from dark adaptation? No - it isn't. If you had your eyes dilated with drops, the measurement is likely incorrect. #46 Alex McConahay
The response was then classified on a scale from 1 to 9, positively correlated with nociception [9]. Nociceptive stimulation inhibits the Edinger-Westphal nucleus to dilate the pupillary, and the degree of dilation is positively correlated with the intensity of the nociceptive stimulation. Opioid ...
These findings, however, are based on measures of genital responses, which have potential limitations such as volunteer bias and different measurement devices for men and women. The present study introduces a measure that is less affected by these limitations: pupil dilation. We...

The pupillary dilation reflex (PDR) is an objectiveindicator of analgesic levels in anesthetized patients. Through measurement of the PDR during increasing tetanic stimulation (10–60 mA), it is possible to obtain the pupillary pain index (PPI), a score that assesses the level of analgesia.#...
