Adie-Holmes syndrome associated with COVID-19 infection: A case report

open access: yesIndian Journal of Ophthalmology, 2021
With increasing experience, it has been suggested that the SARS-CoV-2 virus has a neurotropic effect. Here, we present a case of a tonic pupil who developed after COVID-19 infection.

A case of Adie’s tonic pupil

open access: yesJournal of Surgery and Medicine, 2021
Adie'nin tonik pupillası; yuvarlak tek taraflı tonik pupilla, genişlemiş ve ışık yanıtı olmayan nöro-oftalmolojik bir bozukluktur. Genellikle idiyopatiktir, ancak enfeksiyon, iltihaplanma ve postganglionik paraneoplastik sinir hasarı ile ilişkilidir. Derin tendon refleks kaybı meydana geldiğinde Holmes-Adie sendromu olarak adlandırılır.

The impact of luminance on tonic and phasic pupillary responses to sustained cognitive load [PDF]

open access: yes, 2017
Pupillary reactions independent of light conditions have been linked to cognition for a long time. However, the light conditions can impact the cognitive pupillary reaction.

Mind the social feedback : effects of tDCS applied to the left DLPFC on psychophysiological responses during the anticipation and reception of social evaluations [PDF]

open access: yes, 2022
The left dorsolateral prefrontal cortex (lDLPFC) is implicated in anticipatory (i.e. during anticipation of emotional stimuli) and online (i.e. during confrontation with emotional stimuli) emotion regulatory processes. However, research that investigates

The primary function of REM sleep [PDF]

open access: yes, 2006
In this paper, the physiological features associated with the different stages of REM sleep and with what information processing researchers have called “effort” and “arousal” are compared.

Isometric exercise facilitates attention to salient events in women via the noradrenergic system

open access: yesNeuroImage, 2020
The locus coeruleus (LC) regulates attention via the release of norepinephrine (NE), with levels of tonic LC activity constraining the intensity of phasic LC responses.

Monitoring Cognitive and Emotional Processes Through Pupil and Cardiac Response During Dynamic Versus Logical Task [PDF]

open access: yes, 2010
The paper deals with the links between physiological measurements and cognitive and emotional functioning. As long as the operator is a key agent in charge of complex systems, the definition of metrics able to predict his performance is a great challenge.

Attentional Disengagement and the Locus Coeruleus – Norepinephrine System in Children With Autism Spectrum Disorder

open access: yesFrontiers in Integrative Neuroscience, 2021
BackgroundDifferences in non-social attentional functions have been identified as among the earliest features that distinguish infants later diagnosed with autism spectrum disorder (ASD), and may contribute to the emergence of core ASD symptoms ...

Pupillometry Reveals the Role of Arousal in a Postexercise Benefit to Executive Function

open access: yesBrain Sciences, 2021
A single bout of aerobic exercise improves executive function; however, the mechanism(s) underlying this improvement remains unclear. Here, we employed a 20-min bout of aerobic exercise, and at pre- and immediate post-exercise sessions examined executive

Cognitive and Ocular Factors Jointly Determine Pupil Responses under Equiluminance.

open access: yesPLoS ONE, 2016
Changes in pupil diameter can reflect high-level cognitive signals that depend on central neuromodulatory mechanisms. However, brain mechanisms that adjust pupil size are also exquisitely sensitive to changes in luminance and other events that would be ...
