Tsukuba, Japan—Although increased fatigue from physical exercise arises from various exercise-induced factors, it is assumed that the lack of dynamic physical exertion in esports would lead to a ...

The horizontal axis represents the time elapsed following the presentation of the image, while the vertical axis denotes the degree of change in pupil diameter relative to the image presentation. A ...

New research shows that during moments of lost focus after poor sleep, the brain releases a wave of cerebrospinal fluid (CSF)—the same cleansing process that normally occurs during deep sleep.

The science of pupillometry takes a common intuition — that you can tell a lot about someone when you look them in the eye — and makes it concrete, measurable, and extraordinarily useful. By combining ...

Sleep deprivation reliably caused attention failures despite their obvious dangers, like the potentially fatal consequences ...

New findings suggest that measuring changes in how pupils react to light could help predict recovery from depression and personalize transcranial magnetic stimulation (TMS) treatment of major ...

Pupil size in response to light could serve as a biomarker for concussion, according to a study published in Life. “A concussive injury to the brain is associated with changes in the PLR [pupillary ...

New findings from researchers at UCLA Health suggest that measuring changes in how pupils react to light could help predict recovery from depression and personalize transcranial magnetic stimulation ...

The researchers also found several other physiological events linked to attentional lapses, including decreases in breathing and heart rate, along with constriction of the pupils. They found that ...
