Measurement of the electrotonic length constant in cultured muscle fibres.
The measurement of passive electrical membrane properties in cultured muscle cells is complicated by the fact that the electrotonic length in these cells often exceeds their actual length, leading to serious deviations from the simple infinite cable behaviour. By using very short current pulses for these measurements and integrating the responses, the cells can be made to behave as infinite cables.
