摘要：

In electrophysiology, field potential (FP) recordings give us macroview information of the brain activities. In this research, the tail of the rat was stimulated and the evoked FP at the thalamus was recorded. In order to record the neural activities in thalamus that is deeper than cortex, it is provided the multi-electrode probing, based on the new microfabrication with high-density, recording simultaneously in a group of neural tissue. A multi-channel recording system was also developed to process a huge FPs. According to the Possion equation, FPs were further analyzed to obtain current source density (CSD) mapping to locate the responsive area. The developed contour or CSD mapping software for FP was a valuably tool for neuroscience research.
