Correlation coefficient, τ, determined between all possible pairs of bump parameters under control conditions from two representative WT cells

A.		t1	t2	t3	Jmax
	t2	0.05
	t3	0.04	0.04
	Jmax	0.21	0.05	0.42**
	tlat	0.21	−0.02	0.19	−0.08

B.		t1	t2	t3	Jmax
	t2	−0.05
	t3	0.14	0.02
	Jmax	0.28*	0.24	0.44**
	tlat	−0.23	0.03	0.21	−0.10

Conditions were: −70 mV, 1.5 mm Ca²⁺. Values represent 106 bumps in A and 76 bumps in B. The only consistently significant correlation observed was between J_max and decay half-time t₃

^**P < 0.001. Weaker apparent correlations e.g. t₁ and J_max

^*P≈ 0.02 were not reproducible. Similar results were obtained in 7 cells (only 4 for t_lat).
