Heartbeat Sensing: A Unique Ability of the Blind.

Blind individuals have a heightened ability to sense their own heartbeat compared to sighted individuals, according to a study by researchers at Karolinska Institutet in Sweden and Jagiellonian University in Poland. The study suggests that blindness leads to a heightened ability to feel signals from inside the body. The researchers will continue to study how blind individuals perceive their own bodies and examine if structural changes in the visual cortex may explain the increased ability to sense signals from the inside of the body.
