The authors examined the neural function of a postmeningitic deaf–blind patient who regained his hearing with a multichannel cochlear implant. Auditory stimuli activated the temporal cortices of both sides in a manner similar to that of controls, reflecting the successful recruitment of the auditory cortex after implantation. The patient’s occipital lobes were deactivated during the tactile language task, the results of which were completely different from those before cochlear implantation.
