The goal of this research project is to investigate the cortical reorganization of children with single sided deafness (SSD) following intervention with a cochlear implant, compared to a group of children with SSD but not fitted with a cochlear implant, and a group of children with normal hearing. Single sided deafness significantly affects cortical symmetry, as it results in an increased dominant representation of the normal ear compared to the deaf ear. However, research shows that early intervention in children with single sided deafness can restore the hemispheric representations of bilateral auditory input in the auditory cortex. Using EEG-based objective measures, we will investigate the binaural restoration at the subcortical and cortical level of the auditory pathway in children who are four years and older. Neural activity captured by the multi-channel EEG will be used to construct functional network models of cortical processes.
