In cat the relation between various behaviours and the spectral properties of the hippocampal EEG was investigated. Both EEG and behaviour were quantified and results were evaluated statistically. Significant relationships were found between the properties of the hippocampal EEG and motor acts (walking, sitting, eating, stepping and eye movements). These results were compared with those obtained in dog under similar experimental circumstances. Species differences were found particularly regarding the fact that in the cat a dissociation between frequency and amplitude parameters was obtained for some behaviours; this may explain why appreciable differences in the visual interpretation of EEG records of different species are often reported. A simple model of the modulation of hippocampal EEG by brainstem inputs is presented. Particular attention is paid to species differences regarding the anatomy and physiology of the pathways involved in this modulation. It is concluded that in cat a strong relation exists between the modulation of spectral properties of hippocampal EEG and vestibular inputs and/or eye movements. The effects of body acceleration on hippocampal EEG are put in evidence and related to theories of hippocampal function.
在猫身上，研究了各种行为与海马脑电活动（EEG）频谱特性之间的关系。对EEG和行为都进行了量化，并对结果进行了统计学评估。发现海马EEG的特性与运动行为（行走、坐、进食、踏步和眼球运动）之间存在显著关系。将这些结果与在类似实验条件下狗身上获得的结果进行了比较。发现了物种差异，特别是在猫身上，某些行为的频率和振幅参数之间出现了解离；这可能解释了为什么经常报道不同物种EEG记录的视觉解读存在明显差异。提出了一个脑干输入对海马EEG进行调制的简单模型。特别关注了参与这种调制的通路在解剖学和生理学方面的物种差异。得出的结论是，在猫身上，海马EEG频谱特性的调制与前庭输入和/或眼球运动之间存在密切关系。证明了身体加速度对海马EEG的影响，并将其与海马功能理论联系起来。
