Connection probabilities, PN-PN connections

Type Parameters	PN to PN
Connection range (µm)	<=50	[50,100]	[100,200]	[200,600]
Connectivity	3%	2%	1%	0.5%

Connectivity data are from Abatis et al. (2017). For all chemical synaptic connections, we designed axonal conduction delay to be $Del=\frac{Dis}{v}+min{i}_{del}+fluc+dt$, where Del denotes calculated conduction delay (ms), Dis is the intersoma distance (µm), v denotes conduction velocity (mm/ms, 1 mm/ms was used in this study), mini_deldenotes minimal conduction delay (mini_del= 0.8 ms was used in this study), fluc denotes random fluctuation of conduction delay [ms, fluctuation of uniformly distribution of (−0.1,0.1) ms was used in this study], and dt denotes simulation time step, with dt = 0.05 ms was used in this study.
