Cerebral Activation and Bilateral Stimulation by Cochlear Implantation in Bilateral Deaf Adults
August 26, 2019 updated by: Hospices Civils de Lyon
The primary objective to this study is to describe bilateral auditory information processing in profoundly deaf patients with bilateral cochlear implants compared with normal hearing patients.
Assumption used is that due to the central consequences of bilateral deafness on binaural auditory information central processing, time between activation of the two cochlear implants is a decisive factor in bilateral implantation compared to unilateral implantation
