Other parameter values in the model at the reference temperature (11°C)

	AB Cell	PD Cell
C	9.0 nF	12.0 nF
[Ca]	τCa = 303 ms, S = 0.418 μM/nA, Camin = 0.5 μM	τCa = 300 ms, S = 0.515 μM/nA, Camin = 0.5μM
Icoup	gaxial = 0.3 μS, ggap = 0.75 μS	gaxial = 1.05 μS, ggap = 0.75 μS

I_coup refers to the current passing between coupled electrical compartments — g_axial and g_gap refer to the soma-axon and soma-soma coupling conductances, respectively (see schematic in Fig. 2). All other symbols are defined in the methods section.
