Invisible light inside the natural blind spot alters brightness at a remote location

open access: yesScientific Reports, 2018
The natural blind spot in the visual field has been known as a large oval region that cannot receive any optical input because it corresponds to the retinal optic disk containing no rod/cone-photoreceptors. Recently, stimulation inside the blind spot was

PHARMACOLOGICAL STUDIES ON PUPILLARY REFLEX DILATATION

open access: yesJapanese Journal of Pharmacology, 1965
Concerning the role of sympathetic and parasympathetic mechanisms in reflex dilatation of the pupil elicited by painful stimuli, there have long been many arguments. One group of authors, for example, Bechterew (1) and Braunstein (2) concluded that the pupillary dilatation resulting from painful stimuli was caused solely by inhibition of the third ...

A missense variant (P10L) of the melanopsin (OPN4) gene in seasonal affective disorder [PDF]

open access: yes, 2009
Background: Melanopsin, a non-visual photopigment, may play a role in aberrant responses to low winter light levels in Seasonal Affective Disorder (SAD).

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

open access: yesThe 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.

Comparison of acute non-visual bright light responses in patients with optic nerve disease, glaucoma and healthy controls. [PDF]

open access: yes, 2015
This study examined the effect of optic nerve disease, hence retinal ganglion cell loss, on non-visual functions related to melanopsin signalling. Test subjects were patients with bilateral visual loss and optic atrophy from either hereditary optic ...

Research progress on the depth of anesthesia monitoring based on the electroencephalogram

open access: yesIbrain, Volume 11, Issue 1, Page 32-43, Spring 2025.
Electroencephalogram (EEG) can noninvasive, continuous, and real‐time monitor the state of brain electrical activity, and the monitoring of EEG can reflect changes in the depth of anesthesia (DOA). The development of artificial intelligence can enable anesthesiologists to extract, analyze, and quantify DOA from complex EEG data.

Untersuchung der Eignung nozizeptiver Reflexe zur Quantifizierung der endogenen Schmerzmodulation und zur Beurteilung der Analgesie unter Allgemeinanästhesie [PDF]

open access: yes, 2019
Introduction: Nociceptive reflexes like the nociceptive flexion reflex (NFR) or the pupillary dilation reflex (PDR) are used to measure pain and nociception in wake patients and patients under sedation.

Organic neuromorphic electronics powering intelligent sensory and edge computing systems

open access: yesInfoMat, EarlyView.
Organic electronic materials are promising candidates for neuromorphic sensing applications, including chemical, physical, visual, and multimodal sensing, owing to their mechanical softness, biocompatibility, and intrinsic ionic–electronic coupling.
