Figure 3. Electrophysiological characterization of ion currents during growth in oocytes of Styela plicata.

Figure 3

A) Average current-voltage relationship (I/V curve) generated from depolarizing voltage steps between −70 and +20 mV from an holding potential of −80 mV. The current was maximally activated by voltage step to −20 mV in the GV-A and GV-B and to −30 mV in GV-C. All I/V curves are obtained by averaging the peak current for fifteen oocytes. Error bars indicate S.E. B) The maximum peak inward current (means ± S.E.) recorded at the activation step of −20 mV in GV-A and GV-B, while the value was −30 mV in GV-C (a vs b vs c P<0.01).
