Eye dilation with a mydriatic is a complicated physiologic effect. Not only is pupillary constriction “paralysed” but so is the focusing mechanism. Pharmacological pupillary dilatation is therefore not the same as dark adaptation, and would explain why it would not be helpful for astronomic viewin...
duration, which they then subtracted from the relevant portion of their pupil data. This average response typically consisted of a brief dilation, followed by constriction, followed by an approximately 2-s return to baseline pupil size, though the timing and magnitude of the changes were a functio...
Pupil dilation has been reliably identified as a physiological marker of consciously reportable mental effort. This classical finding raises the question of whether or not pupil dilation could be a specific somatic signature of conscious processing. In order to explore this possibility, we engaged healt...
Pupil dilations and constrictions are governed by the ANS [40]. Thus, PD exhibits changes under stress situations [46] and literature suggests that it can positively contribute to the problem posed herein. Liao et al. [26] affirmed that pupils are dilated more often under stress situations. ...
relatively larger (dilation) or smaller (constriction) pupil sizes in response to a stimulus category. Viewing Behavior We first examined the viewing patterns that the persons in the scenes elicited in male and female observers. To examine this, the percentage fixations to the ROIs were calculated...

Conversely, relaxation can result in pupil constriction. Pupil anatomy is also fairly straightforward. Pupil contraction and dilation are controlled by two smooth muscles of the iris. The pupillary reflex is what allows the pupil to constrict and dilate involuntarily. It is important to remember the...
Rather, the pupil diameter increased slightly and this pupil dilation developed gradually without clear latency locked to the stimulus onset (see Fig. 2a,“small disk” at “BS”). This effect could be attributed to autonomic responses mediated by arousal signals conveyed by sympathetic nerves, ...
However, once you step out of the dark room, your pupils will return to normal or adjust to the new level of brightness. In other words, mydriasis is atemporarydilation of the pupils in response to light. Blown pupils are dilated very widely andfixed, meaning they do not respond to an...
