This paper deals with the electrical characteristics of microelectrodes for measuring intracellular potentials. Assuming the constant distributed capacitance and the resistance which is inversely proportional to the square of the radius, the admittance parameters and the equivalent circuit for a microelectrode as a distributed RC element.are derived. Some comparisons are made between the theoretical and the experimental values, together with some discussions on the relationship between the electrical characteristics and the possible shape of the microelectrode as revealed by the photographs taken using ordinary and electron microscopes.
