To identify which of the two groups of the C-fiber conducts pain and/or warm we used the techniques of the single-fiber recording and the antidromic collision test. The conduction velocity of the action potentials recorded could not be determined by our results of the single-fiber recording. Nevertheless, the results from the latter technique suggest that the two types of sensation were transmitted by both of the two groups of the C-fiber. Additionally, the dematomes of the rat’s tail were determined and a thermo and a mechanical stimulators were implemented during the project.application/pdf36607 bytesapplication/pdfzh-TW國立臺灣大學醫學工程學研究所動作電位皮節逆向碰撞Action Potentialdematomeantidromic collision testreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/29520/1/872314B002318M08.pdf
