Goldfish with implanted intracranial electroencephalographic (EEG) electrodes showed high-voltage slow activity of 6-9 Hz and a low-voltage fast activity of 16-24 Hz when resting in the dark. The former frequency was prevalent in the telencephalon, diencephalon, and midbrain but remained only in parts of the midbrain and cerebellum when the fish was left resting in an illuminated environment. In this latter condition the 16-24 Hz activity became predominant. Presentation of two stimuli, the onset of illumination and the passage of a moving edge across the source of illumination, caused bradycardia and a reduction in ventilatory rate, associated with behavioral arousal in this animal. An increase in the amplitude of 16-24 Hz activity in the EEG also occurred, most evident in the anterior and posterior tectum and dorsomedial and posterior telencephalon. Anterior tectal EEGs, on arousal, had the shortest latency and longest duration and were most resistant to habituation on repeated presentation of the moving-edge stimulus, the dorsomedial telencephalon showing similar characteristics to a lesser degree. It is suggested that these areas may be intimately concerned with the arousal response in teleosts.
植入颅内脑电图（EEG）电极的金鱼在黑暗中静止时，显示出6 - 9赫兹的高电压慢活动和16 - 24赫兹的低电压快活动。前一种频率在端脑、间脑和中脑普遍存在，但当鱼在光照环境中静止时，仅在中脑和小脑的部分区域保留。在后一种情况下，16 - 24赫兹的活动变得占主导地位。呈现两种刺激，即光照开始和移动边缘穿过光照源，会导致心动过缓和呼吸频率降低，同时伴有该动物的行为觉醒。脑电图中16 - 24赫兹活动的振幅也会增加，在前庭和后顶盖以及背内侧和后端脑最为明显。在前庭顶盖脑电图中，觉醒时潜伏期最短、持续时间最长，并且在重复呈现移动边缘刺激时最不易产生习惯化，背内侧端脑在较小程度上表现出类似特征。有人认为，这些区域可能与硬骨鱼的觉醒反应密切相关。
