Grayson Clamp was born completely deaf, missing the cochlear nerve that helps the ear process sound to the brain. His parents, Len and Nicole, enrolled him in a research trial at the University of North Carolina after a failed cochlear implant, hoping to find another way to help.
Three weeks ago, he received an auditory brain stem implant where a microchip is implanted in the brain to facilitate sound through tubes from his ears. Grayson is the first child to try such a procedure.
"It's been phenomenal," his father said whose first words to his son were, "Daddy loves you."
