摘要
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 。
The optical imaging based on intrinsic signals is the one with the best spatial resolution among in vivo brain imaging techniques. It becomes a powerful tool for studying fuctional architecture of the cortex in a large scale. We describe the method using this technique to show the orientation columns in the cat visual cortex. Basically, it is also suitable for studying functional organization of other cortex.
