In an epileptic patient with depth electrodes placed in the hippocampal formation we observed the following: (1) There existed a significant peak in the theta band of the hippocampal EEG of this subject under a number of behavioural circumstances. (2) Four different behaviours were performed at two degrees of intensity. Whenever the values of a certain spectral parameter associated with a low or a high intensity behaviour showed a significant difference, the higher value corresponded with the more intense version of the behaviour. (3) The frequency and rhythmicity of the hippocampal theta component during writing was consistently higher than during sitting or walking. The amplitude was smaller. (4) In a word association task the amplitude, frequency and rhythmicity showed a significant rise during the period of silence immediately following the question and preceding the answer.
在一名将深度电极置于海马结构的癫痫患者中，我们观察到以下情况：(1) 在多种行为情况下，该受试者海马脑电的θ频段存在一个显著峰值。(2) 以两种强度水平执行四种不同行为。每当与低强度或高强度行为相关的某个频谱参数值显示出显著差异时，较高的值对应于更强烈版本的行为。(3) 书写过程中海马θ成分的频率和节律始终高于坐着或行走时。其幅度较小。(4) 在词语联想任务中，在问题之后紧接着答案之前的沉默期，幅度、频率和节律均出现显著上升。
