💨 Abstract

Researchers at Karolinska Institutet in Sweden have discovered a new mechanism that affects pupil size: breathing. The pupil is smallest during inhalation and largest during exhalation, which could theoretically affect vision. This mechanism is cyclical, ever-present, and requires no external stimulus. The discovery may contribute to a better understanding of how vision and attention are regulated.
