当存在 8Hz 左右频率范围内的振荡时,大鼠海马细胞表现出特征性的相位依赖性放电。基于theta相编码是由神经活动同步产生的假设,分析海马和内嗅皮层的自联想网络模型,以探索情景记忆的机制。 θ 节律中的相位编码可以即时获取经历过的事件,包括时间和空间内容。与啮齿类动物和灵长类动物的电生理学数据的进一步比较表明,θ 振荡在记忆编码和情景事件的在线处理中可能发挥作用。
Rat hippocampal cells exhibit characteristic phase-dependent firings when oscillation in frequency range around 8Hz is present. Based on the hypothesis that theta phase coding is generated by synchronization of neural activities, an autoassociative network model of the hippocampus and the entorhinal cortex was analyzed to explore mechanisms underlying episodic memory. Phase coding in theta rhythm enables instantaneous acquisition of experienced events including temporal and spatial contents. Further comparison with electrophysiological data from both rodents and primates suggests a possible role of theta oscillations in memory encoding and online processing of episodic events.
