説明

Action potentials from a single nerve preparation were recorded in a electric field covered with mineral oil through bipolar or monopolar lead, and their forms were discussed. The single nerve was obtained from terminal Pacinian corpuscle preparation of the cat's mesentery. Namely, the preparation with a length of senory axon was free by dissection from mesenteic tissue and set up for mechanical stimulation. Conductive action potential originating at the corpuscle was recorded through one pair of platinum electrode or unipolar lead in the oil pool.<BR>When the bipolar lead was applied, its potential showed the triphasic. After cutting central end of the nerve, then it changed into diphasic potential. If the unipolar lead was used, the potential showed the diphasic and after cutting, it changed into monophasic potential. The above reasons were demonstrated and explained by using the electrochemical model, Yamagiwa Lillie's nerve model and Matumoto's nerve model.
