早期的个人观察表明，在颞叶中存在类似阿尔法的节律。这种节奏与后方的阿尔法节奏和中央的Mu节奏没有关系，因此，它可以被称为“第三节奏”。这种活动在头皮导联中是检测不到的，但在骨缺损的情况下可能会变成“突破节律”。使用硬膜外电极评估一名年轻成人作为可能的颞叶切除术的候选者，产生了一个异常好的“第三节奏”的演示。事实上，有两种节律性的变形体活动。其中一例位于颞叶上方较前方，左侧(主要累及癫痫)半球上方较突出。这种节律经常出现在颞部头皮电极上，并被认为是一种异常现象。另一种类型的节律性活动在颞叶中段最大，右侧(癫痫影响较小)发育较好，基本上在头皮导联检测不到。这种节奏似乎是真正的生理“第三节奏”。这种节奏的响应度仍不清楚。当病人唱歌时，右侧出现衰减。
Earlier personal observations have indicated the existence of an alpha-like rhythm in the temporal lobe. This rhythm shows no relationship to the posterior alpha and the central mu rhythm; for this reason, it may be called the "third rhythm." This activity is undetectable in scalp leads but may turn into a "breach rhythm" under bone defects. The assessment of a young adult as a possible candidate for temporal lobectomy with the use of epidural electrodes yielded an unusually good demonstration of the "third rhythm." As a matter of fact, there were two types of rhythmical alphoid activity. One of them was more anteriorly located over the temporal lobe and more prominent over the left (epileptologically chiefly involved) hemisphere. This rhythm was often visualized in the temporal scalp electrodes and was felt to be an abnormal phenomenon. The other type of rhythmical activity was maximal in the midsection of the temporal lobe, better developed on the right (epileptologically less affected) side and essentially undetectable in scalp leads. This rhythm appears to be the true physiological "third rhythm". The responsiveness of this rhythm remains unclear. Attenuation on the right side occurred while the patient was singing.
