利用平均技术在猫记录了听皮层纯音调频诱发电位,并测定了对不同载波频率F的调频反应阈△F_m。调频诱发电位的波形与短纯音诱发电位的相似,也有“给”、“撤”、“给-撤”等几种类型。△F_m因载波频率及皮层记录点的不同而异,最佳者中、高频可以在0.01F以下,低频在10赫以下,与文献上用条件反射方法测得的结果大致相当。高、中、低频纯音调频反应灵敏点在AI区的分布互相交错,不像调谐反应那样有排列整齐的频率区域特性。
Mean catastrophic tone induced evoked potentials were recorded in cats using the averaging technique, and the FM response threshold ΔF_m for different carrier frequencies, F, was determined. FM evoked potential waveform and short pure tone evoked potential similar, but also “to”, “withdraw”, “to - withdrawal” and several other types. △ F_m varies with carrier frequency and cortical recording point. The best medium and high frequency can be below 0.01F and the low frequency below 10Hz, which is roughly equivalent to that obtained by the literature using conditional reflection method. High, medium and low frequency pure tone FM response points in the AI area of the distribution of staggered, unlike the tuning reaction as neatly arranged frequency region characteristics.
