    Sammanfattning : Electrocochleography (ECoG) is an objective method to evaluate cochlear electrophysiology. The recordings are considered to reflect the mechano-electric processes of the cochlea, and can indicate the presence of suspected endolymphatic hydrops. LÄS MER

    Sammanfattning : Using an in vitro model of the guinea pig, the temporal bone preparation, cochlear physiology was studied. By perfusion of the scala tympani with oxygenated culture medium, the responses of the hearing organ to sound stimuli were maintained over several hours and the functional state was followed by monitoring the electrophysiological parameters cochlear microphonics (CM) and summating potential (SP).
