Table 2. Bursting statistics: Comparison between preBötC intrinsic bursters and Model 1-induced bursters.

Neuron type	Burst frequency (Hz)	bAHP amplitude (mV)	Burst duration (ms)	Action potential count	Spike interval (ms)
Model 1–induced bursters (n = 24)	0.22 ± 0.09	2.3 ± 0.5	516.3 ± 104.5	16.7 ± 3.7	33.6 ± 5.7
Natural bursters (n = 22)	0.21 ± 0.07	2.7 ± 1.4	452.1 ± 144.2	20.4 ± 5.6	23.7 ± 5.4
P value	0.36	0.17	0.098	0.006	0.0001

The recordings were obtained as described in Fig. 1 E (intrinsic bursters; n = 22) and Fig. 6 B (induced bursters; n = 24). The values were calculated by averaging over five consecutive bursts in each neuron. For induced bursters, the average G_NaP value that was required to induce rhythmic bursting with at least five action potentials per burst was 1.4 ± 0.7 nS (range: 0.5–2.7 nS). The data are mean ± SD.
