Pupil-based arousal self-regulation: impact on physiological and affective responses to emotional stimuli [PDF]

open access: yesTranslational Psychiatry
Pupil-based biofeedback has been shown to enable healthy participants to volitionally control locus coeruleus-mediated arousal. The locus coeruleus is considered a critical player in the central stress circuitry and dysfunctions in the system, causing ...

Multimodal biomarker based on temporal complexity of eye movements and pupil diameter in attention-deficit/hyperactivity disorder. [PDF]

open access: yesPLOS Mental Health
Attention-deficit/hyperactivity disorder (ADHD) is one of the most prevalent neurodevelopmental disorders without established biomarkers. Pupil diameter, regulated by the locus coeruleus-norepinephrine (LC-NE) system, and eye movements controlled by ...

The diagnostic significance of pupillary reflex pathways: insights from classical examination and advanced pupillometry [PDF]

open access: yesFrontiers in Neuroscience
Background/objectivesThe pupil, a dynamic ocular structure, serves as a critical indicator of neurological and ophthalmological function. This interdisciplinary review explores the anatomical, physiological, and pathological aspects of pupillary reflexes

Contribution of pupillary light reflex assessment to Glasgow Coma Scale for prognostication in patients with traumatic brain injury [PDF]

open access: yesJournal of Neurocritical Care, 2021
Background Glasgow Coma Scale (GCS) and the pupillary light reflex (PLR) are important prognostic tools for traumatic brain injury (TBI). This study compared the predictability of GCS, GCS plus manual PLR (GCS-P), GCS plus Neurological Pupil index (GCS ...

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

Pupil response to accommodation and convergence in healthy children and adolescents of various age groups and autonomic nervous system tone

open access: yesJournal of Ophthalmology, 2020
Background: As there is close association between pupil response and accommodation during gaze fixation on an object at any distance, it is important to assess accommodative pupil response both in healthy children and in those with accommodative ...

Increased Pupil Size during Future Thinking in a Subject with Retrograde Amnesia

open access: yesBrain Sciences, 2022
Recent research has assessed pupil size during past thinking in patients with retrograde amnesia. Building on this research, we assessed pupil size during future thinking in a retrograde amnesia patient.

Pupil response to accommodation and convergence in children and adolescents with accommodative disorders

open access: yesJournal of Ophthalmology, 2020
Background: As there is close association between pupil response and accommodation during gaze fixation on an object at any distance, it seems interesting to study pupil response to accommodation in patients with accommodative disorders.
