We studied the effect of binaural, contralateral and ipsilateral stimulation on middle- and long-latency auditory-evoked magnetic fields using trains of 40-Hz clicks. The stimuli evoked both a transient response (N100m) and a 40-Hz response, which presumably reflects coalescence of middle-latency responses. Binaural stimuli elicited significantly larger 40-Hz responses and sustained fields than contralateral stimuli. N100m amplitudes did not differ between binaural and contralateral stimulation; the dipole moments were even smaller to binaural than contralateral stimuli. Responses to the ipsilateral stimuli were always the smallest.
我们使用40赫兹的短声序列研究了双耳、对侧和同侧刺激对中长潜伏期听觉诱发磁场的影响。这些刺激诱发了一个瞬态反应（N100m）和一个40赫兹反应，后者可能反映了中潜伏期反应的融合。与对侧刺激相比，双耳刺激诱发的40赫兹反应和持续磁场明显更大。双耳刺激和对侧刺激之间的N100m振幅没有差异；双耳刺激的偶极矩甚至比对侧刺激更小。对同侧刺激的反应总是最小的。
