资料来源:Ulivi, A. F., et.al。活体小鼠背侧海马CA1的纵向双光子成像。J. 对比实验 (2019)
该视频演示了活小鼠中荧光标记的锥体神经元的纵向双光子成像, 展示了树突和树突棘的准备、套管对齐和成像,以研究海马 CA1 区域的神经元结构。
所有涉及动物模型的程序均已由当地机构动物护理委员会和 JoVE 兽医审查委员会审查。
2. 成像

图 1:体内深部脑光学成像的准备工作。(A)。成像套管示例的顶视图(左)和侧视图(右)。成像插管具有透明的玻璃底部,允许从光学角度进入海马体。(B)。制备的示意图描述突出显示了成像套管、CA1 PN(锥体神经元)和从背侧到腹侧的三层纤维的相对位置。(C, D)。成像过程中成像装置 (C) 和动物固定 (D) 的示意图描述。
