The middle (10-50 ms) and long (50-600 ms) latency periods of the auditory evoked potential (AEP) were investigated in muscle-paralyzed, artificially respired cats with respect to two issues: (1) the distribution of components across the skull, and (2) the effects of changing stimulus intensity on component latencies and amplitudes. The distributional data were gathered during a behavioral study in which four behavioral tasks related to classical pupillary conditioning were used to vary attentional and arousal processes. The distributions across the skull surface (averaged across tasks) of 12 peaks and troughs (P10, N13, P17, N22, P31, N41, P55, N70, N100, N140, P260 and N520) and seven principal components derived from the set of waveforms collected during this experiment are reported. Both peak amplitudes and principal component scores were distributed differentially across the skull surface. In the second experiment, acoustic stimulus intensity was varied, and AEPs collected from a vertex and temporal electrode site. In general, increasing stimulus intensity had a stronger influence on the earlier portions of the AEP, where increased amplitude and decreased latency was the rule, than on later ones. The relationships between cat and human AEP components were discussed based on both the data presented in this paper and in previous papers.
在肌肉麻痹、人工呼吸的猫身上，研究了听觉诱发电位（AEP）的中潜伏期（10 - 50毫秒）和长潜伏期（50 - 600毫秒），涉及两个问题：（1）各成分在颅骨上的分布，以及（2）刺激强度变化对成分潜伏期和波幅的影响。分布数据是在一项行为研究中收集的，该研究使用了与经典瞳孔条件反射相关的四项行为任务来改变注意力和觉醒过程。报告了在颅骨表面（任务平均）12个峰和谷（P10、N13、P17、N22、P31、N41、P55、N70、N100、N140、P260和N520）以及从本实验收集的一组波形中导出的七个主成分的分布情况。峰波幅和主成分得分在颅骨表面的分布均存在差异。在第二个实验中，改变了声刺激强度，并从头顶和颞部电极部位收集AEP。一般来说，增加刺激强度对AEP较早部分的影响更强，在较早部分，波幅增加和潜伏期缩短是规律，而对较晚部分的影响则较弱。基于本文及先前论文中呈现的数据，讨论了猫与人AEP成分之间的关系。
