中文摘要：
大量证据表明星形胶质细胞通过钙信号积极参与脑功能.在星形胶质细胞的功能研究中,诱导其产生钙信号是一项关键技术.然而,传统的刺激方法不能同时满足非接触、无损、高时空精度的要求,本研究小组提出的飞秒激光刺激星形胶质细胞的方法能够弥补这些不足.在此基础上,验证了该方法在海马神经网络水平上研究星形胶质细胞功能的应用.混合培养的海马神经网络中,星形胶质细胞被飞秒激光刺激后：（1）诱导神经元同步钙振荡;（2）即时性干预神经元自发同步钙振荡;（3）调制神经元的高频自发同步钙振荡.因此,通过演示光诱导的星形胶质细胞钙信号调控海马神经元同步钙振荡,证明飞秒激光刺激方法能够为星形胶质细胞在神经网络中的功能研究提供强有力的工具.
