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.

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.

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 ...

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.

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.

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.

Behavioural and neural signatures of perceptual decision-making are modulated by pupil-linked arousal

eLife, 2019
The timing and accuracy of perceptual decision-making is exquisitely sensitive to fluctuations in arousal. Although extensive research has highlighted the role of various neural processing stages in forming decisions, our understanding of how arousal ...

Germline TP53 Mutations Causing Diamond–Blackfan Anemia: A French Report

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Diamond–Blackfan anemia is a rare congenital erythroblastopenia typically caused by mutations in ribosomal protein genes. Recently, gain‐of‐function mutations in TP53 have been identified as a novel cause of Diamond–Blackfan anemia. We report two French patients who both harbored a heterozygous TP53 deletion (NM_000546.5: c.1077delA; p ...

Insulation for daydreams: a role for tonic norepinephrine in the facilitation of internally guided thought. [PDF]

PLoS ONE, 2012
Although consciousness can be brought to bear on both perceptual and internally generated information, little is known about how these different cognitive modes are coordinated.

Holographic assembly of quasicrystalline photonic heterostructures

, 2005
Quasicrystals have a higher degree of rotational and point-reflection symmetry than conventional crystals. As a result, quasicrystalline heterostructures fabricated from dielectric materials with micrometer-scale features exhibit interesting and useful ...
