Positron Emission Tomography Imaging of Brain Reorganisation of the Central Auditory Cortex in Asymetrical Profound Deaf Patient With a Cochlear Implantation.
Sponsor: University Hospital, Toulouse
Summary
Our main objective is to study how the extent of reorganization of the central auditory system is related to the binaural integration in cochlear implanted subjects with asymmetric hearing loss. Subjects with asymmetric hearing loss treated with a cochlear implant and a control group of normal hearing subjects will perform two tests for binaural integration (speech recognition in noise and spatial localization) and two tasks of non-linguistic sounds perception.
