将大脑作为一个整体，观察周围神经受到刺激后大脑反应的动态过程，是深入了解脑功能的基础，也是一个科学难题。本研究发展了一种新型大鼠脑皮层诱发电位微创正交记录方法，结果显示，在该方法下，刺激大鼠正中神经、尺神经和桡神经及其分支，首次获得了可重复、具有不同波形特点、可辨别的脑皮层诱发电位图谱，并将其时空变化规律以可视化的方式呈现出来。此外本研究也记录了正中神经离断4个月后，大鼠脑皮层诱发电位的变化。结果表明，大脑皮层对周围神经刺激的反应具有精确和可重复的时空顺序。本实验方法和波形图谱可作为测试平台用于探索周围神经系统和脑中枢神经系统之间的整体功能交互与动态重塑的时相机制。

Observing the dynamic progress of the brain in response to peripheral nerve stimulation as a whole is the basis for a deeper understanding of overall brain function; however, it remains a great challenge. In this work, a novel mini-invasive orthogonal recording method is developed to observe the overall evoked cortex potential (ECP) in rat brain. A typical ECP atlas with recognizable waveforms in the rat cortex corresponding to the median, ulnar, and radial nerve trunks and subdivided branches is acquired. Reproducible exciting temporal–spatial progress in the rat brain is obtained and visualized for the first time. Changes in the ECPs and exciting sequences in the cortex four months after median nerve transection are also observed. The results suggest that the brain's response to peripheral stimulation has precise and reproducible temporal–spatial properties. This resource can serve as a testbed to explore the overall functional interaction and dynamic remodeling mechanisms between the peripheral and central nervous systems over time.
