Pupillometry as tool to assess cognitive and affective processing in aging
Brain DisordersThe present manuscript synthesizes research using pupillometry to assess cognitive and affective processing in the aging population. There are two main findings: first, pupil size tends to enlarge as the cognitive load increases in older adults and a ...

Multifiber Array‐Based Photometry System for Multiregional Functional Mapping in the Mouse Brain
European Journal of Neuroscience, Volume 63, Issue 12, June 2026.Existing fiber photometry approaches suffer from invasiveness and limited scalability. A newly developed multifiber array‐based photometry system allows targeting multiple brain regions with less invasiveness. The system was validated in two jGCaMP8s‐expressing mouse lines by monitoring GABAergic neural population activity across multiple brain regions

Mesopic pupillometry in pre-LASIK patients by a placido-disc topographer and hartmann-shack aberrometer [PDF]
, 2021 Introduction: Precise pupillometry is crucial to determine ablation optical zone (OZ) size selection in LASIK. Significant difference in the selection induces unwanted postoperative night visual disturbance.

Evaluation of Cholinergic Deficiency in Preclinical Alzheimer’s Disease Using Pupillometry
Journal of Ophthalmology, 2017 Cortical cholinergic deficiency is prominent in Alzheimer’s disease (AD), and published findings of diminished pupil flash response in AD suggest that this deficiency may extend to the visual cortical areas and anterior eye.

European Journal of Neurology, Volume 33, Issue 6, June 2026.This graphical abstract presents the review process (including 41 studies). It highlights the use of machine learning techniques in adults with CDH, such as unsupervised learning for phenotype discovery and supervised learning for diagnosis classification. The figure summarizes the strengths and limitations of each approach, along with key clinical and

Stimulus Predictability and Liking Enhance Auditory–Motor Encoding and Memory for Melodies
Annals of the New York Academy of Sciences, Volume 1560, Issue 1, June 2026.Musical predictability significantly affects how we judge music. Through a combination of expectations and surprises, music shapes the pleasure we experience while listening. This pleasure can be measured using metrics of physiological arousal such as pupil size.
