Voltage-clamp analysis of membrane currents and excitation-contraction coupling in a crustacean muscle

A single fibre preparation from the extensor muscle of a marine isopod crustacean is described which allows the analysis of membrane currents and simultaneously recorded contractions under two-electrode voltage-clamp conditions. We show that there are three main depolarisation-gated currents, two ar...
