Untersuchungen zur Selektivität von neuentwickelten mehrkanaligen Innerohrelektroden bei intracochlearer elektrischer Stimmulation

cochlear implant situation, selectivity of neural auditory excitation. - The cochlear implantation is an admitted rehabilitation method for patients with profound sensorineural hearing loss. This inner ear prosthesis replaces the function of the damaged hair cells by direct electrical stimulation of the auditory nerve. Thereby the transmission quality of the electrical intracochlear information depends on the spatial and temporal resolution. A good temporal resolution can be achieved by using a high stimulus rate. Avoiding interaction between the seperate electrode channels, a high spatial resolution capacity should be aquired. For this reason Advanced Bionics Corporation (Sylmar, CA, USA) developed new electrode types to...
