脑内源信号光学成像术是目前为止空间分辨率最高的一种活体脑成像技术 ,它为大范围皮质的功能构筑研究提供了有力工具。本文介绍了应用这一技术显示活体猫视皮质的方位功能柱的方法 ,此方法基本上也适用于其他皮质的功能构筑研究 Brain endogenous signal optical imaging is by far the highest spatial resolution of a living brain imaging technique that provides a powerful tool for studying the functional architecture of a wide range of cortices. This article presents a method for using this technique to visualize azimuthal functional cortices in living cats. This method is also basically applicable to functional curation studies of other cortices
