A correlational study between the dominant frequencies in the spontaneous local field potential and the single unit's best modulation frequency (BMF) for periodic click train stimulation in the primary auditory cortex of the cat is presented. Data were obtained from 251 single units recording in 29 cats. The correlation between spindle frequency (mean 8.2 Hz) and BMF (mean 9.3 Hz) was significant (r2 = 0.58, p < 0.0001). The limiting click-following rate was negatively correlated with the strength of the spindle rhythm: the longer the oscillation the lower the limiting rate. This suggests that the click-following responses of the primary auditory cortex depends as much on ongoing autonomous activity as it does on stimulus-induced activity.
本文介绍了一项关于猫初级听觉皮层中自发局部场电位的主导频率与周期性点击序列刺激下单神经元的最佳调制频率（BMF）之间的相关性研究。数据来自对29只猫的251个单神经元记录。纺锤体频率（平均8.2Hz）与BMF（平均9.3Hz）之间的相关性显著（r2 = 0.58，p < 0.0001）。极限跟随点击率与纺锤体节律强度呈负相关：振荡持续时间越长，极限率越低。这表明初级听觉皮层的跟随点击反应既依赖于持续的自主活动，也依赖于刺激诱发的活动。
