20世纪70年代，人们主要用脑电图法来研究听觉反应的偏移量，但从那时起，就没有人特别注意过它们。在使用脑磁图(MEG)设备的研究中，据我们所知，只有三项关于听觉OFF反应的研究，并且从未观察到纯音引起的ON反应和OFF反应的来源位置之间的显著差异。用122道头盔形磁力计测量了5名健康受试者对不同频率纯音刺激的听觉诱发磁场，并比较了听觉N100m-Off(100ms左右磁Off-Response)和N100m-On的声源位置分布。它们的空间分布非常接近，但也有显著的差异。(C)1998年Rapid Science Ltd.
OFFSET auditory responses were investigated by electroencephalography mainly in the 1970s, but since then no particular attention has been paid to them. Among the studies using magnetoencephalography (MEG) devices there are, to our knowledge, only three studies of the auditory off-response, and no significant variance has ever been observed between the source locations of on- and off-responses elicited from pure tones. We measured auditory evoked magnetic fields (AEFs) to various frequency pure tone stimulation in 5 healthy subjects with a 122-channel helmet-shaped magnetometer, and compared the distributions of the source locations of auditory N100m-Off (magnetic off-response around 100 ms) with those of N100m-On. Their spatial distributions were quite close to each other, and yet they were significantly different. (C) 1998 Rapid Science Ltd.
