Changes in the auditory cortex of children receiving gene therapy for deafness

Children with DFNB9 deafness receiving gene therapy in either one ear or both ears exhibited enhanced activation in parts of the auditory speech cortex, which occurred as early as four weeks after surgery, as well as an improvement in measures of their mental development.
