Linking the superior colliculus to pupil modulation

CA Wang, DP Munoz - Modern Pupillometry: Cognition, Neuroscience …, 2024 - Springer
Pupil size is becoming a popular index in basic and clinical investigation because it is
modulated by various sensory, cognitive, and affective processes. Recent research has …

Fatigue and arousal modulations revealed by saccade and pupil dynamics

JT Chen, YC Kuo, TY Hsu, CA Wang - International journal of …, 2022 - mdpi.com
Saccadic eye movements are directed to the objects of interests and enable high-resolution
visual images in the exploration of the visual world. There is a trial-to-trial variation in …

Investigating the role of human frontal eye field in the pupil light reflex modulation by saccade planning and working memory

TY Hsu, HY Wang, JT Chen, CA Wang - Frontiers in Human …, 2022 - frontiersin.org
The pupil constricts in response to an increase in global luminance level, commonly referred
to as the pupil light reflex. Recent research has shown that these reflex responses are …

Emphasis on peripheral vision is accompanied by pupil dilation

A Vilotijević, S Mathôt - Psychonomic Bulletin & Review, 2023 - Springer
People are best able to detect stimuli in peripheral vision when their pupils are large, and
best able to discriminate stimuli in central vision when their pupils are small. However, it is …

Effort drives saccade selection

D Koevoet, L Van Zantwijk, M Naber, S Mathôt… - bioRxiv, 2024 - biorxiv.org
What determines where to move the eyes? We recently showed that pupil size, a marker of
noradrenaline release, reflects the effort associated with making a saccade ('saccade costs') …

Investigating causal effects of pupil size on visual discrimination and visually evoked potentials in an optotype discrimination task

HH Chin, YH Tai, R Yep, YH Chang, CH Hsu… - Frontiers in …, 2024 - frontiersin.org
Pupil size primarily changes to regulate the amount of light entering the retina, optimizing
the balance between visual acuity and sensitivity for effective visual processing. However …

Social attention as a general mechanism? Demonstrating the influence of stimulus content factors on social attentional biasing.

EJ Pereira, E Birmingham, J Ristic - Journal of Experimental …, 2022 - psycnet.apa.org
Humans spontaneously attend to faces and eyes. Recent findings, however, suggest that
this social attentional biasing may not be driven by the social value of faces but by general …

Covert shifts of attention towards the visual periphery induce pupil dilation

A Vilotijević, S Mathôt - bioRxiv, 2022 - biorxiv.org
Previous studies have suggested that pupil size increases with covert shifts of attention to
the peripheral as compared to the (para) foveal visual field, ie, with increasing “attentional …

The oculomotor signature of expected surprise

D Drążyk, M Missal - Scientific Reports, 2022 - nature.com
Expected surprise, defined as the anticipation of uncertainty associated with the occurrence
of a future event, plays a major role in gaze shifting and spatial attention. In the present …
