A shows a single arrest potential, B two such potentials 45 msec apart. Time scale equals 100 msec; amplitude scales, 3 mV (extracellular) and 20 mV (intracellular). The duration of ciliary arrest probably corresponds fairly closely to the duration of depolarization of the cells, but this relationship has not been accurately deter- mined. To do so would require simultaneous monitoring of the ciliary beati

The duration of ciliary arrest probably corresponds fairly closely to the duration of depolarization of the cells, but this relationship has not been accurately deter- mined. To do so would require simultaneous monitoring of the ciliary beating with a photomultiplier, a technique used for the first time in a metazoan by Murakami and Takahashi (1975). During normal ciliary activity the membrane potential is steady and unwavering as in the ascidian Corclla (Mackie et a/., 1974) and in Mvtilns (Murakami and Takahashi, 1975).. t i BI i . j > Jinn.
