Synapse parameters
Name	Value	Description
J ± δJ	Intra-areal connections: 87.8 ± 8.8 pA, cortico-cortical connections scaled as Jcc = χJ, χ ∈ [1, 2.5] cortico-cortical connections onto inhibitory populations scaled as $J_{\text{cc}}^{\mathcal{I}}={\chi }_{\mathcal{I}}\chi J$	excitatory synaptic strength
g	g = 16 in Fig 2A and 2B, g = 11 in all other figures	relative inhibitory synaptic strength
de ± δde	1.5 ± 0.75 ms	local excitatory transmission delay
di ± δdi	0.75 ± 0.375 ms	local inhibitory transmission delay
d ± δd	$d=s/v_{\mathrm{t}}\pm \frac{1}{2}s/v_{\mathrm{t}}$	inter-area transmission delay, with s the distance between areas
vt	3.5 m/s	transmission speed
