伽玛频段（20-100 Hz）的网络振荡可能在成人大脑神经活动的计时和协调中发挥核心作用，但它们在发育过程中的出现仍未被探索。此外，基于脑电图（EEG）的警惕状态分类[主动睡眠（AS）、安静睡眠（QS）或清醒（W）]被认为只有在产后第二周后才有可能。我们现在报告在出生后第 5-10 天（P）自由活动的大鼠的 CA3 区存在自发海马伽玛振荡。最初，在 P5 时，在海马内脑电图记录的时频分析中看到伽马振荡很简短（
Network oscillations in the gamma-frequency band (20-100 Hz) may have a central role in the timing and coordination of neural activity in the adult brain, yet their appearance in the course of development has remained unexplored. Moreover, electroencephalogram (EEG)-based classification of the vigilance states [active sleep (AS), quiet sleep (QS), or awake (W)] has been thought to be possible only after the second postnatal week. We now report the presence of spontaneous hippocampal gamma oscillations in the area CA3 of freely moving rats at postnatal days (P) 5-10. Initially, at P5, the gamma oscillations were seen in time-frequency analyses of intrahippocampal EEG recordings as brief (
