神经细胞在体内的高分辨率成像技术为神经科学研究带来了巨大的进步。在这里,我们报告了一个新的实验平台,在手术植入的微光学流体装置的帮助下,可以研究活体小鼠的完整大脑;作为神经元和外部世界之间的接口。新开发的设备提供了通过双光子激光扫描显微镜对神经元精细结构进行长期和高分辨率观察所需的功能,以及将化学物质或药物直接输送到大脑的微流体。一项通过双光子释放谷氨酸刺激单突触的概念验证实验和随后几天对树突棘萎缩的观察表明,该技术具有很好的应用前景。
The high-resolution imaging of neural cells in vivo has brought about great progress in neuroscience research. Here, we report a novel experimental platform, where the intact brain of a living mouse can be studied with the aid of a surgically implanted micro-optical fluidic device; acting as an interface between neurons and the outer world. The newly developed device provides the functions required for the long-term and high-resolution observation of the fine structures of neurons by two-photon laser scanning microscopy and the microfluidic delivery of chemicals or drugs directly into the brain. A proof-of-concept experiment of single-synapse stimulation by two-photon uncaging of caged glutamate and observation of dendritic spine shrinkage over subsequent days demonstrated a promising use for the present technology.
