An Environmental Rhythm Influences the Pupil Dynamics (IMAGE)
Caption
The pupil opens and closes quickly in the rhythm of the incoming light (purple). If there is also a light-independent environmental rhythm (orange), which here is given by the temporal arrangement of the faces in pairs, the pupil is also controlled by this more complex rhythm. In this case, it remains further open, as if a pair should not be interrupted by a contraction of the pupil.
