【摘要】 为探索我国神经磁场检测的临床应用前景，作者在零磁实验室利用低温超导量子干涉仪测定了９例正常人和２例重度混合性耳聋患者的颞叶脑磁图及声诱发脑皮层磁反应，成功地描记了颞叶脑磁图和脑磁反应，波形清晰，相当稳定。自发脑磁图波形振幅在±１００ｆＴ之间。在我们的测试条件下，用１０００Ｈｚ的短纯音诱发的脑磁反应可分为Ｐ１、Ｎ１……Ｎ４共８个波，各波潜伏期个体差异很小，主波为Ｎ２、Ｐ３、Ｎ３波，潜伏期分别为６５、１１８、１７５ｍｓ，振幅在±１５ｆＴ左右。认为此项检测有其潜在的临床应用前景。更多还原

【Abstract】 n magnetic shield room, 9 normal subjects weremeasured by magnetoencephalography (MEG) and au-ditory evoked magnetic field (AMF) with supercon-ducting quantum device (SQUID). In our experiment ,the magnitudes of MEG were between + 100 fT and- 100 fT and an AMF evoked with 1 kHz tone bursthad 8 stable waves. The main waves were N2 , P3 , N3with latencies 65 , 118 , 175 ms and magnitudes - 13 ,+ 15 , -12 fT. The latencies of waves showed smalldeviations. The magnitudes of waves were about± 15fT. We also found that the two lateral records ofcountralateral AMFs have revert waveforrns in the lasttwo subjects.更多还原
