DOI: 10.1007/s10792-018-0879-1
Abstract: PurposePupillometry should be performed under conditions as close to natural viewing as possible. The present study aimed to determine whether pupil size in binocular open-view settings can be predicted based on pupil size measured using… read more here.

DOI: 10.1016/j.concog.2021.103089
Abstract: To examine the relationship between visual imagery and autobiographical memory, eye position and pupil size were recorded while participants first searched for memories and then reconstructed the retrieved memories (Experiment 1), or only searched for… read more here.

Pupil Size Coupling to Cortical States Protects the Stability of Deep Sleep via Parasympathetic Modulation
Sign Up to like & getrecommendations! Published in 2018 at "Current Biology"
DOI: 10.1016/j.cub.2017.12.049
Abstract: Summary During wakefulness, pupil diameter can reflect changes in attention, vigilance, and cortical states. How pupil size relates to cortical activity during sleep, however, remains unknown. Pupillometry during natural sleep is inherently challenging since the… read more here.

DOI: 10.1038/s41598-024-52486-6
Abstract: Moment-to-moment fluctuations in arousal can have large effects on learning and memory. For example, when neutral items are predictive of a later reward, they are often remembered better than neutral items without a reward association.… read more here.

DOI: 10.1038/s41598-024-70895-5
Abstract: Pupillometry is widely used to measure arousal states. The primary functional role of the pupil, however, is to respond to the luminance of visual inputs. We previously demonstrated that cognitive effort-related arousal interacted multiplicatively with… read more here.
