Abstract
An auditory-evoked magnetic field was recorded before and during tinni tus remission induced by an intravenous lidocaine injection. One and 4 kHz probe tones were presented monaurally in four tinnitus patients, and the responses were recorded using a 122-channel magnetometer. Thre e normal volunteers were also examined as controls. In tinnitus patien ts, the N100 m peak became sharper, while there was no marked change e xcept for slight reduction in amplitude in normal subjects. Tinnitus r emission by lidocaine may be related to attenuation of a masking-like effect of tinnitus on the sound-evoked responses.
