Recent studies have revealed that mild forms of exercise, such as yoga or walking, can improve mood and enhance executive function, which involves the brain's prefrontal cortex and refers to the ...

Researchers have uncovered a key mechanism linking breathing to pupil size. Published in The Journal of Physiology, the study reveals that the pupil contracts during inhalation and dilates during ...

Researchers at Karolinska Institutet in Sweden have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing. The study, published in the Journal of Physiology, ...

For over a century, scientists believed that light, focus distance, and cognitive effort were the main forces behind changes in pupil size. But a new discovery adds breathing to that list. Researchers ...

This study examined the effect of optic nerve disease, hence retinal ganglion cell loss, on non-visual functions related to melanopsin signalling. Test subjects were patients with bilateral visual ...

Researchers at Karolinska Institutet in Sweden have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing. The study, published in The Journal of Physiology, ...

Mild exercise like yoga improves mood and executive function, but the neural mechanisms were unclear. Using pupillometry, researchers found that pupil size changes during very light exercise predict ...
