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

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

Morphometric study of the ciliary ganglion and its pertinent intraorbital procedure
Folia Morphologica, 2020 BACKGROUND: Ciliary ganglion (CG) can be easily injured without notice in many intraorbital procedures. Surgical procedures approaching the lateral side of the orbit are at risk of CG injury which results in transient mydriasis and tonic pupil.
