Everyone knows the feeling - the chills when you hear that one song, or the painful shivering at the sound of nails against a chalkboard. Now, imagine if your body continuously heard sound through its skin.
Sherrilyn Roush is the first reported individual to have developed this form of synesthesia, a neurological mix-up of senses, after a stroke that left her numb in the left side of her body. Researcher Tony Ro was lucky enough to study her incredible anomaly, and his theoretical findings are monumental. He believes sense of hearing may have evolved from a sense of feeling, and that Roush’s merging of sound and touch is just an exaggerated version of what happens in all of our brains. Although speculative, it’s possible that what scientists now interpret as a merger of sound and touch might actually be a reflection of an earlier state in which the two senses were one.
