Transcript

从

记录设置中的孤立小鼠海马体开始。

将

局部场电位或 LFP 电极降低到海马体表面。该电极可以检测表明神经元网络活动的细胞外电压变化。

插入电极并观察电压变化。

进一步插入下层并观察有节律的神经元网络活动,称为 θ 振荡。

将

第二个电极放置在同一层内与第一个电极一定距离的位置,以记录更广泛区域的 θ 振荡。

监控相当远距离内 θ 振荡的同步。这显示了神经元网络的连通性。

要记录通过不同海马层的 θ 振荡,首先将第二个电极放置在上层。

逐渐降低电极穿过不同的层。

记录并观察振荡模式的反转,这反映了海马体每一层独特的神经元组成和功能。

在此过程中,将 LFP 电极降低到海马体表面。将LFP电极推进过金字塔层,观察细胞外尖峰活性的增加。检测到单个神经元的单个单位放电。

进一步降低电极,并注意当尖端穿过放射状动脉时,尖峰再次开始消失。观察到θ频率范围内清晰可见的网络振荡变得明显,并且随着记录位置通过辐射降低而达到最大幅度。

为了测试整个 CA1 区域自发 θ 振荡的空间特性,将第二个 LFP 电极放入 CA1 位点,并观察 CA1 θ 振荡在很远的距离上同步。

为了测试跨海马层的θ振荡的特性,请在CA1辐射位点中留下一个参比电极。从天层正上方开始,将第二个电极降低到锥体细胞层并穿过辐射体。观察 LFP 信号在金字塔层上的逐渐反转。
