摘要

研究了慢性植入大鼠在清醒和矛盾睡眠状态下，中隔电损伤对海马背侧θ波活动的影响。实验结果表明，根据其定位的不同，间隔损伤可以:(1)在不抑制矛盾睡眠的情况下消除清醒θ节律;(2)在不抑制清醒状态的情况下消除矛盾的睡眠θ节律。这些结果表明，存在两种具有不同解剖生理学基础和不同功能意义的θ波活动:一种与清醒有关，另一种与矛盾睡眠有关。

[Experimental dissociation between hippocampal theta activity in wakefulness and hippocampal theta activity in paradoxal sleep in the rat].

The effects of electrolytic lesion of the septum on the theta activity of the dorsal hippocampus were studied in the chronically implanted Rat during wakefulness and paradoxical sleep. The experimental results show that depending on its localization, septal lesion can either: (1) eliminate the wakefulness theta rhythm without suppressing that of paradoxical sleep; (2) eliminate the paradoxical sleep theta rhythm without suppressing that of wakefulness. These results suggest that there are two kinds of theta activity having different anatomophysiological bases and a different functional significance: one associated with wakefulness and the other with paradoxical sleep.
