Why Other Senses May Be Heightened in Blind People
People who are blind really do have enhanced abilities in their other senses, according to a new, small study. The research used detailed brain scans to compare the brains of people who were blind to the brains of people who were not blind.
The study involved people who were either born blind or became blind before age 3. The scans showed that these individuals had heightened senses of hearing, smell and touch compared to the people in the study who were not blind.
