Relationship between Human Pupillary Light Reflex and Circadian System Status. [PDF]

PLoS ONE, 2016
Intrinsically photosensitive retinal ganglion cells (ipRGCs), whose photopigment melanopsin has a peak of sensitivity in the short wavelength range of the spectrum, constitute a common light input pathway to the olivary pretectal nucleus (OPN), the ...

Falling pupil numbers and school closures: Setting a research agenda for a new era of precarity

British Educational Research Journal, EarlyView.
Abstract This paper explores the significant phenomenon of decreasing pupil numbers in England due to lower birth rates and the impact of a school closure on a school community. It then discusses how the sociology of education might research this major issue.

The value of pupillary diameter in evaluating pain perception after awakening in patients undergoing general anesthesia during orthopedic surgery

BMC Anesthesiology
Background The pupillary response to tetanic electrical stimulation reflects the balance between nociceptive stimulation and analgesia. Although pupillary pain index (PPI) was utilized to predict postoperative pain, it depended on tetanic stimulation and

Human pupillary light reflex during successive irradiation with 1-ms blue- and green-pulsed light

Journal of Physiological Anthropology, 2017
Background In the human retina, the contribution of intrinsically photosensitive retinal ganglion cells (ipRGCs) to the regulation of the pupillary response remains poorly understood.

Effects of Exposure to Intermittent versus Continuous Red Light on Human Circadian Rhythms, Melatonin Suppression, and Pupillary Constriction [PDF]

, 2014
Exposure to light is a major determinant of sleep timing and hormonal rhythms. The role of retinal cones in regulating circadian physiology remains unclear, however, as most studies have used light exposures that also activate the photopigment melanopsin.

A physiological marker of recognition memory in adults with autism spectrum disorder? The Pupil Old/New Effect [PDF]

, 2020
This study investigated the pupil Old/New effect in individuals with Autism Spectrum Disorder (ASD) and typical development (TD). Participants studied verbal and visual meaningful and meaningless materials in black and white on a computer screen.

Internationalising the teacher education curriculum: An analysis of syllabi and student experiences

The Curriculum Journal, EarlyView.
Abstract Internationalisation has increasingly become a key dimension of quality in initial teacher education (ITE) programmes. Although it is recognised as a means to strengthen future teachers' competencies and expand their professional knowledge, it remains underdeveloped in practice.

The effect of opioids on the light-off pupillary reflex

Journal of Anesthesia, Analgesia and Critical Care
Objective We examined the relationship between modeled opioid concentration and quantitative pupillary measures during remifentanil infusion sequences with particular attention to the “light-off” (LO) reflex. Methods Ten volunteer subjects were recruited

Use of the Neurological Pupil Index to Predict Postoperative Visual Function After Resection of a Tuberculum Sellae Meningioma: A Case Report. [PDF]

, 2019
The Neurological Pupil index (NPi) is a standardized method for evaluating pupil reactivity that removes inter-examiner variability. Changes in the NPi can predict clinical deterioration in patients with traumatic brain injury (TBI); however, its use to ...

Differential monocular vs. binocular pupil responses from melanopsin-based photoreception in patients with anterior ischemic optic neuropathy. [PDF]

, 2015
We examined the effect of anterior ischemic optic neuropathy (AION) on the activity of intrinsically photosensitive retinal ganglion cells (ipRGCs) using the pupil as proxy.
