Fig. 7. Effect of Ca2+ current on K+ current. (A)
Superposition of two current traces associated with depolarisations to +30 mV
with a 200 ms interval. The pulse duration was 25 ms. (B) K+
current component obtained by subtracting the second current record from the
first current record in A. The bath solution was 3Ca-ASW containing 4 µmol
l1 TTX, and the pipette solution was K-asp. Cell membrane
capacitance (Cm)=110.4 pF.
