Anatomical Considerations and Long-Term Effects of Electrical Stimulation

  • Chapter
Cochlear Implants: Auditory Prostheses and Electric Hearing

Part of the book series: Springer Handbook of Auditory Research ((SHAR,volume 20))

Abstract

There is a consensus that achieving high levels of speech intelligibility with auditory prostheses requires the use of several independent channels of stimulation, each engaged in the transmission of limited bandwidth information (see Zeng, Chapter 1; Wilson, Chapter 2; Shannon et al., Chapter 8). Several types of multichannel cochlear prostheses have been designed with the objective of selectively exciting discrete sectors of the auditory nerve by placing individual electrodes at several sites along the cochlear spiral. Most of these devices utilize the tonotopic organization of the primary afferent auditory neurons within the scala tympani, one of the spiral fluid channels of the cochlea, which is accessible from the middle ear via entrance from the round window or through an opening created just anterior to the window (see Niparko, Chapter 3). As described by Wilson in Chapter 2, several multichannel devices have been developed and used in clinical populations.
