Application of stem cell-derived neurons to the deaf cochlea
Dr Bryony Nayagam
Successful replacement of damaged auditory neurons will have widespread health benefits by increasing the numbers of suitable candidates for cochlear implantation and by improving the benefits currently derived from this prosthesis. The goal of this program of research is to reverse the deafness-induced loss of auditory neurons, using stem cells as a source of replacement cells. A key step toward this goal is to determine whether these stem cell-derived neurons are capable of functional integration in the deaf auditory pathway, and whether their integration can be enhanced following electrical stimulation from a cochlear implant. Projects under this research theme involve multi-disciplinary, cross-institutional collaborations between A/Prof Mirella Dottori, A/Prof James Fallon and Prof Rob Shepherd.
