PupilEXT: Flexible Open-Source Platform for High-Resolution Pupillometry in Vision Research

Frontiers in Neuroscience, 2021
The human pupil behavior has gained increased attention due to the discovery of the intrinsically photosensitive retinal ganglion cells and the afferent pupil control path’s role as a biomarker for cognitive processes. Diameter changes in the range of 10–

Pupillometry in Chagas disease

Arquivos Brasileiros de Oftalmologia, 2018
We investigated parasympathetic innervation abnormalities of the iris sphincter and ciliary muscles in chronic Chagas disease by measuring pupillary diameter and intraocular pressure.A group of 80 patients with Chagas disease was compared with 76 healthy individuals without chagasic infection.

Digital Pupillometry in Normal Subjects [PDF]

Neuro-Ophthalmology, 2016
The aim of this study was to evaluate the pupil size of normal subjects at different illumination levels with a novel pupillometer. The pupil size of healthy study participants was measured with an infrared-video PupilX pupillometer (MEye Tech GmbH, Alsdorf, Germany) at five different illumination levels (0, 0.5, 4, 32, and 250 lux).

Inhibitory Decay and Supercritical Brain Dynamics During Sleep Deprivation

Advanced Science, EarlyView.
Sleep deprivation progressively shifts human brain dynamics from near‐critical toward supercritical states, as revealed by neuronal avalanche analysis of resting‐state fMRI. These changes track subjective sleep pressure rather than vigilance lapses and show marked network heterogeneity. A circuit model suggests that reduced inhibitory efficacy provides

Atypical Attentional Effort During Visual Search in Autistic Adults: Evidence From Task‐Evoked Pupillary Responses

Autism Research, EarlyView.
ABSTRACT According to prevalent views, autistic individuals have a stronger tendency to allocate attention to details, as supported by reports of enhanced visual search performance. However, both the dynamics and the types of information involved in attentional guidance in autism are not fully understood.

Exploring the feasibility of pupillometry training and perceptions of potential use for intracranial pressure monitoring in Uganda: A mixed methods study.

PLoS ONE
IntroductionTraumatic brain injury (TBI) accounts for the majority of Uganda's neurosurgical disease burden; however, invasive intracranial pressure (ICP) monitoring is infrequently used. Noninvasive monitoring could change the care of patients in such a

Investigation of the behavior of tinnitus patients under varying listening conditions with simultaneous electroencephalography and pupillometry

Brain and Behavior
Objective This study aims to control all hearing thresholds, including extended high frequencies (EHFs), presents stimuli of varying difficulty levels, and measures electroencephalography (EEG) and pupillometry responses to determine whether listening ...
