Publication facts (s) having Bevan MD, Wilson CJ (1999) as Paper having this fact

2 A long duration component of the spike afterhyperpolarization determined the period of the oscillation and was generated by an apamin-sensitive calcium-activated potassium current..”
3 A persistent sodium current was the source of current during the depolarizing phase of the oscillation.”
4 Thus there is a steady-state calcium current contributing to the depolarization phase of the oscillation but small in comparison with the sodium current."
