Pupillometry and P3 index the locus coeruleus– noradrenergic arousal function in humans [PDF]

, 2011
The adaptive gain theory highlights the pivotal role of the locus coeruleus–noradrenergic (LC-NE) system in regulating task engagement. In humans, however, LC-NE functional dynamics remain largely unknown.

William John Adie: the man behind the syndrome [PDF]

, 2014
William John Adie was an Australian neurologist in the early 20th century responsible for extensively describing the tonically dilated pupil associated with absent deep tendon reflexes – both features of a syndrome that now bears his name. In addition to

A Rare Case in the Emergency Department: Holmes-Adie Syndrome

Turkish Journal of Emergency Medicine, 2015
SUMMARY: Holmes-Adie syndrome (HAS) is a rare syndrome characterized by tonic pupil and the absence of deep tendon reflexes. HAS was first described in 1931 and is usually idiopathic, with incidences reported to be 4-7 per 100,000.

Temporal dynamics of motivation-cognitive control interactions revealed by high-resolution pupillometry [PDF]

, 2013
Motivational manipulations, such as the presence of performance-contingent reward incentives, can have substantial influences on cognitive control. Previous evidence suggests that reward incentives may enhance cognitive performance specifically through ...

Individual differences in infant oculomotor behavior during the viewing of complex naturalistic scenes [PDF]

, 2014
Little research hitherto has examined how individual differences in attention, as assessed using standard experimental paradigms, relate to individual differences in how attention is spontaneously allocated in more naturalistic contexts.

Tonic and phasic transcutaneous auricular vagus nerve stimulation (taVNS) both evoke rapid and transient pupil dilation

Brain Stimulation
Background: Transcutaneous auricular vagus nerve stimulation (tVNS or taVNS) is a non-invasive method of electrical stimulation of the afferent pathway of the vagus nerve, suggested to drive changes in putative physiological markers of noradrenergic ...

Dissociable mappings of tonic and phasic pupillary features onto cognitive processes involved in mental arithmetic.

PLoS ONE, 2020
Pupil size modulations have been used for decades as a window into the mind, and several pupillary features have been implicated in a variety of cognitive processes.

Pupil Diameter Tracks Lapses of Attention. [PDF]

PLoS ONE, 2016
Our ability to sustain attention for prolonged periods of time is limited. Studies on the relationship between lapses of attention and psychophysiological markers of attentional state, such as pupil diameter, have yielded contradicting results.

Tonic Pupil and Corneal Anesthesia after Vitrectomy and Encircling Band for Retinal Detachment in an Ex-Premature Child

Case Reports in Ophthalmology, 2010
An 11-year-old boy presented with a total retinal detachment in his right eye. He had a bilateral 360° argon laser treatment for an active retinopathy of prematurity performed after his birth.

Interactions between visceral afferent signaling and stimulus processing [PDF]

, 2015
Visceral afferent signals to the brain influence thoughts, feelings and behaviour. Here we highlight the findings of a set of empirical investigations in humans concerning body-mind interaction that focus on how feedback from states of autonomic arousal ...
