From pupil to the brain: New insights for studying cortical plasticity through pupillometry
Frontiers in Neural Circuits, 2023 Pupil size variations have been associated with changes in brain activity patterns related with specific cognitive factors, such as arousal, attention, and mental effort.

Pupillometry in auditory multistability
PLOS ONE, 2021 In multistability, a constant stimulus induces alternating perceptual interpretations. For many forms of visual multistability, the transition from one interpretation to another (“perceptual switch”) is accompanied by a dilation of the pupil. Here we ask whether the same holds for auditory multistability, specifically auditory streaming. Two tones were

Development of reference intervals for pupillometry in healthy dogs
Frontiers in Veterinary Science, 2022 BackgroundPupillometry, the measurement of pupil size and reactivity to a stimulus, has various uses in both human and veterinary medicine. These reflect autonomic tone, with the potential to assess nociception and emotion.

Pupillometry in Infancy Research [PDF]
Journal of Cognition and Development, 2016 The human pupil is a small opening in each eye that dilates in response not only to changes in luminance, but also to novel events. Therefore, changes in pupil diameter are an attractive measure in studies on infants’ and young children’s physical and social cognition.

Luminance effects on pupil dilation in speech-in-noise recognition.
PLoS ONE, 2022 There is an increasing interest in the field of audiology and speech communication to measure the effort that it takes to listen in noisy environments, with obvious implications for populations suffering from hearing loss.

Detection of opioid effect with pupillometry [PDF]
Autonomic Neuroscience, 2021 Opioids produce pupillary constriction but their impact on pupillary unrest and the dynamic parameters of the pupillary light reflex have not been characterized. Given the increasing use of portable pupillometers for care of critically ill patients, it is important to distinguish between opioid effects on the pupil versus those that have been reported ...

IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023 Hybrid brain-computer interfaces (HBCI) combining eye-tracker has attracted the attentions of researchers in target recognition. However, there are still many issues to be addressed in rapid sequence visual presentation (RSVP) tasks, such as the effect ...
