%X A novel bursting, intermittent period 1 spiking, was observed in the experimental neuronal pacemaker. It showed the characteristics as follows: First, its spike trains randomly transiting between continual period 1 spiking and intermittency. Second, the duration of the intermittency, the duration and the number of the continual period 1 spikes exhibited large variability, indicating that the firing pattern was not periodic. Last, it lay between period 1 spiking and at rest. Intermittent period 1 spiking similar to experiments was simulated in the FHN(FitzHugh-Nagumo) model driven by quasi-monochromatic noise (QMN) with a long basic period. The statistical character, the changing regularity and the parameter region of two intermittent period 1 spiking were similar. The results showed that the intermittent period 1 spiking might be induced by an oscillation similar to the QMN with a long basic period.
