Sympathetic and Parasympathetic Modulation of Pupillary Unrest

Frontiers in Neuroscience, 2020
Pupillary unrest is an established indicator of drowsiness or sleepiness. How sympathetic and parasympathetic activity contribute to pupillary unrest is not entirely unclear.

Updating Traumatic Brain Injury Classification for Surgeons: Integrating the CBI‐M Framework Into Trauma and Acute Care Practice

World Journal of Surgery, Volume 50, Issue 7, Page 2042-2049, July 2026.
Traumatic brain injury (TBI) remains a major cause of death and disability worldwide. Traditional classification based on the Glasgow Coma Scale (GCS) provides a shared clinical language but insufficiently captures the biological heterogeneity, imaging variability, and contextual modifiers that influence outcomes.

Early Versus Late Wake‐Up Call After Out‐Of‐Hospital Cardiac Arrest: Protocol for a Multicenter Randomized Comparison Within the Danish Out‐of‐Hospital Cardiac Arrest (DANOHCA) Trial

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 6, July 2026.
ABSTRACT Background Survivors of out‐of‐hospital cardiac arrest (OHCA) who remain comatose after return of spontaneous circulation are routinely sedated and mechanically ventilated during early post‐resuscitation care. Although prolonged sedation has traditionally been considered necessary, contemporary normothermia‐based temperature control allows ...

Stimulation pupillometry as a predictor of the nociceptive response and a tool for comparing regional blockades during thoracoscopic operations (randomized trial)

Вестник анестезиологии и реаниматологии
Introduction. For effective pain relief in thoracic surgery, accurate monitoring of analgesia is essential. A promising method is pupillometry, which assesses the pupil’s response to pain faster and more accurately than traditional indicators (blood ...

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.

Visual Encoding of Social Cues Contributes to Moral Reasoning in Autism Spectrum Disorder: An Eye-Tracking Study

Frontiers in Human Neuroscience, 2018
Eye-tracking studies suggest that visual encoding is important for social processes such as socio-moral reasoning. Alterations to the visual encoding of faces, for example, have been linked to the social phenotype of autism spectrum disorders (ASDs) and ...
