The eye has always been a fascinating topic for poets, lyricists, and scientists alike. It is often referred to as the window to the soul, as a person’s thoughts and emotions can be revealed through their eyes. However, a new study has found that the eye is also a window to the brain. Researchers at the Georgia Institute for Technology have discovered a correlation between the size of a person’s pupil and their IQ. The study, published in the journal ScienceDirect, analyzed over 500 individuals between the ages of 18 and 35 and found that those with larger pupils were better problem solvers with greater memory and concentration.
The size of a person’s pupil is controlled by the Locus coeruleus, a part of the brainstem responsible for concentration, learning, and communication between the brain and the rest of the body. An active Locus coeruleus is essential for mental abilities and a larger pupil. The study’s findings suggest that a variation in pupil size could serve as an early warning sign for Alzheimer’s disease. Other studies have also linked dysfunction in the Locus coeruleus to Alzheimer’s and ADHD.
The eye is more than just a window to the soul; it is also a window to the brain. The findings of this study shed light on the relationship between the size of a person’s pupil and their mental abilities. Further research could lead to new ways of detecting and treating neurological disorders.
