A study of daily ongoing activity of the sympathic and vagal nerves has shown that 14,6% of this activity are of a rhythmic form (25--35 c/s) arising synchronously in both nerves. Its formation is attended by an enhancement (by 50--100%) of the nerve tone. The appearance of the rhythmic activity bears a non-specific character. A spatial synchronization within the range of 25--35 c/s has been found between the rhythmic activity of the vegetative nerves and that of brain structures. It is suggested that the rhythmic activity of the vegetative nerves reflects a homeostatic mechanism, which is indicative of the appearance of alertness in the nervous system.
一项关于交感神经和迷走神经日常持续活动的研究表明，这种活动的14.6%呈节律性形式（25 - 35次/秒），在两条神经中同步产生。其形成伴随着神经张力增强（50% - 100%）。节律性活动的出现具有非特异性特征。已发现自主神经的节律性活动与脑结构的节律性活动在25 - 35次/秒范围内存在空间同步。有人提出，自主神经的节律性活动反映了一种稳态机制，这表明神经系统中警觉状态的出现。
