The statement "windows to the soul" is frequently used to describe the eyes. There is some neurological truth to this, in reality. Researchers from Baylor College of Medicine in Houston, the Universities of Göttingen and Tübingen in Germany, and other institutions are now able to explain why our internal states, such as fear, excitement, or attention, as well as external stimuli like light, can affect the size of our eye pupils.
The research, which was published in the most recent issue of Nature, sheds light on whether or not our ability to perceive our environment is impacted by these quick, state-dependent changes in eye pupil size that have been observed in animals other than humans.
