In the majority of patients with brain tumours in the area of the third ventricle and a clinical picture characterized by pronounde somnolence, the background EEG showed, along with typical delta-waves, the spindle-shaped theta-activity the form of bilateral synchronous flashes. It was most prominent at parietal leads. This activity increased sharply during sleep and in the soporous state. These data may be of interest in relation to the problem of sleep pathophysiology and pathology. It is suggested that the presence of this activity in combination with delta-waves may constitute a bad prognostic sign in tumours in the area of the third ventricle.
在大多数第三脑室区域患有脑肿瘤且临床表现为深度嗜睡的患者中，背景脑电图除了典型的δ波外，还显示出纺锤形θ活动，呈双侧同步闪光形式。在顶叶导联最为明显。这种活动在睡眠和嗜睡状态下急剧增加。这些数据可能与睡眠病理生理学和病理学问题有关。有人认为，这种活动与δ波同时出现可能是第三脑室区域肿瘤预后不良的迹象。
