chronic imaging of mouse visual cortex using a thinned-skull preparation

在体内成像，利用双光子激光扫描显微镜（2PLSM）允许在完好的大脑活体细胞和神经元突起的研究。这里介绍的技术，允许在几个时间点与微观的决议，允许这是代表多数在中枢神经系统的兴奋性突触后网站的一小结构的树突棘的跟踪（慢性成像）的大脑同一区域的成像。能够清楚地解决以上几个时间点的优良的皮质结构有很多优点，特别是在大脑的可塑性，在突触和电路重塑的形态学变化可能有助于解释底层机制的研究。在这个视频和补充材料，我们将展示一个长期在体内的完整使用一个头骨变薄，准备的脑成像协议。薄头骨准备是一种微创的方法，从而避免了潜在损害的硬脑膜和/或皮质，从而减轻炎症反应的发生。当执行这个协议是正确的，它可以清楚地监测树突棘的特点，在经过一段时间的长期完整的大脑变化。
