摘要: OBJECTIVE Electrical stimulation is normally performed on ears that have no hearing function, i.e., lack functional hair cells. The properties of electrically-evoked responses in these cochleae were investigated several previous studies. Recent clinical developments introduced cochlear implantation (CI) residually-hearing to improve speech understanding noise. present study documents the known physiological differences between electrical cells and spiral ganglion cells, respectively, reviews mechanisms combined electric acoustic ears. DATA SOURCES Literature review from 1971 2016. CONCLUSIONS Compared with pure electroacoustic provides additional low-frequency information expands dynamic range input. Physiological studies document a weaker synchronization evoked activity electrically stimulated compared deaf reduces hypersynchronization activity. findings suggest possibility balancing provided by input using stimulus intensity. Absence distorting acoustic-electric interactions allows exploiting benefits stimulation.
