Probing the electrode-neuron interface with focused cochlear implant stimulation.
Cochlear implants are highly successful neural prostheses for persons with severe or profound hearing loss who gain little benefit from hearing aid amplification. Although implants are capable of providing important spectral and temporal cues for speech perception, performance on speech tests is variable across listeners. Psychophysical measures obtained from individual implant subjects can als...
متن کاملA cochlear implant electrode.
This study has shown that an electrode array can be passed along the hold length of the cochlea if it is inserted through and opening in the scala tympani of the apical turn. The electrode must have the appropriate mechanical properties and some of these were stiffness and extensibility. The electrode and operative approach should be helpful in stimulating the terminal auditory nerve fibres on ...
متن کاملThe Cochlear Implant
The studies on cochlear implants have been conducted in the United States, Austria, Brasil, France, Finland, and some other countries. Up to now, this technique does not seem to have a wide spread application. Indeed it can only apply cases of deafness still presenting sufficient neural remnants to transmit the message. Moreover, the patient must be totally deaf( quasi complete loss of har cel...
متن کاملAdvances to Electrode Pullback in Cochlear Implant Surgery
OBJECTIVE To observe the intracochlear behavior of a cochlear implant electrode insertion technique (called "pullback") in temporal bones. Study Design. Experimental. Settings. Tertiary referral center. METHOD The change of the intracochlear electrode position was investigated under various conditions of an electrode pullback (N = 54) in 9 radiologically, size-estimated temporal bones (TBs). ...
متن کاملA Real Time PC Based Cochlear Implant Speech Processor with an Interface to the Nucleus 22 Electrode Cochlear Implant and a Filtered Noiseband Simulation
Cochlear implants are electronic devices that have enabled individuals with severe to profound hearing losses to regain some hearing. Nearly all of those who receive cochlear implants (CIs) regain the sensation of sound. There is, however, substantial variability in speech perception performance among users of cochlear implants (Staller et al., 1997). One factor that may contribute to the indiv...
