Parameters investigated in their optimization potentials together with their standard value by p_st

	Parameter	Standard Value	Reference
p1	Noise level scale	1.0	(Destexhe et al. 2001)
p2	Fraction of synapses with NMDA	0.9
p3	NMDA-AMPA ratio	0.47	(Myme et al. 2003)
p4	Width of inh. connections, μm	150.0	(Lund et al. 2003)
p5	Max. fraction of GABAB conductance	0.3
p6	Inh. to exc. connections weight scale	1.0	(Thomson et al. 2002)
p7	Exc. to inh. connections weight scale	1.0	(Thomson et al. 2002)
p8	Long-range weight scale	1.0

Standard values for 5 of the parameters could be extracted from the literature. If no reference is given, the standard value was chosen heuristically.
