Ovarian oocytes were isolated from adult mice and intracellular recording was performed using single glass micro-electrodes. The resting potential was - 7.0 +/- 1.8 mV in standard solution, and the oocyte showed a regenerative response at the cessation of hyperpolarizing current pulse. Ca spikes were observed under Na+-free conditions. The overshoot of the spike increased 28 mV for a 10-fold increase in [Ca2+]o and showed saturation as [Ca2+]o was elevated. The spike was insensitive to… CONTINUE READING
