TABLE 2.

Fitting ISI curves, ISI(t) = A(1 − exp(−t/B)), to calculated ISI points from recorded and simulated spike trains for L10 neurons.

Current (nA)	A (ms)		B (ms)		r²
	Exp	Theo	Exp	Theo	Exp	Theo
0.1	31.53	51.37	22.35	48.57	0.092	0.996
0.15	24.74	30.97	27.13	35.90	0.046	0.998
0.2	22.78	22.11	26.55	29.33	0.089	0.980

The small r² values for the experimental data are due to the large variations of ISI values between cells, which are also reflected in the large SD of the measured firing rates (Fig. 2). The values of A, B and r² for 0.2 nA correspond to Fig. 4(e)
