Abstract：
:The membrane characteristics of amphioxus myotome cells were investigated using the chopped-current clamp method. The extremely thin myotome lamellae had a membrane resistance of 2.2 to 7.7 k omega cm2 and a capacity of 0.4 to 1.3 microF/micron2. The steady state current-voltage relation showed outward rectification. In Cl- - and Na+ -free solutions containing 400 mM TEA the input resistance and the time constant increased threefold and Ca2+ -dependent action potentials occurred, indicating the presence of a Ca2+ component in membrane current. It is discussed whether Ca2+ ions entering the cell during the normal action potential may significantly increase the intracellular free Ca2+ concentration.
