A comparative neurophysiological study of the reactivity of hippocampal EEG in dog, cat and human (an epileptic patient with chronically indwelling electrodes) was carried out. In all 3 species the same type of qualitative changes in hippocampal spectral parameters in the theta frequency band (peak frequency, peak amplitude and rhythmicity) in relation to behavioural tasks was encountered. These results were obtained by means of computing triggered averages of spectral parameters in relation to behavioural events. Both in dog and in cat it was found that transitions in behaviour from a low intensity (e.g. sitting) to a high intensity (e.g. walking) motor activity were accompanied by an increase in the value of the afore mentioned spectral parameters. In man a similar relation between such a transition in gross motor behaviour and hippocampal EEG was, however, not observed. The highest frequencies in the theta band appeared in man to be related to "verbal behaviour and writing". In all 3 species the following generalization appeared to hold; when the same behavioural state occurs at different levels of intensity, a higher intensity of the behaviour--as measured in terms of its motor components--is related to higher values for the spectral parameters of the hippocampal EEG.
对狗、猫和人类（一名长期植入电极的癫痫患者）海马体脑电图反应性进行了一项比较神经生理学研究。在所有这三个物种中，均发现与行为任务相关的θ频段（峰值频率、峰值幅度和节律性）海马体频谱参数存在相同类型的定性变化。这些结果是通过计算与行为事件相关的频谱参数触发平均值获得的。在狗和猫中均发现，行为从低强度（如坐着）向高强度（如行走）运动活动转变时，上述频谱参数值会增加。然而，在人类中，未观察到这种总体运动行为转变与海马体脑电图之间的类似关系。在人类中，θ频段的最高频率似乎与“言语行为和书写”有关。在所有这三个物种中，似乎有以下普遍规律成立；当相同的行为状态以不同强度水平出现时，就其运动成分而言，更高强度的行为与海马体脑电图频谱参数的更高值相关。
