Parameters of GRN model for layer formation

Commitment probabilities	C M	C 6	C 5	C 4	C 3	C 2
Human temporal cortex	0.16	0.1	0.2	0.3	0.5	0.7
Rat hindlimb somatosensory cortex	0.08	0.2	0.2	0.3	0.5	0.6
Mouse barrel cortex	0.14	0.3	0.2	0.5	0.5	0.4
Macaque visual cortex	0.11	0.2	0.2	0.5	0.4	0.5
Apoptosis probabilities and Timing threshold	P M	P 6	P 5	P 4	P 3
Human temporal cortex	0.7	0.65	0.55	0.5	0.3
Rat hindlimb somatosensory cortex	0.55	0.6	0.7	0.5	0.5
Mouse barrel cortex	0.45	0.6	0.5	0.4	0.5
Macaque visual cortex	0.6	0.4	0.2	0.5	0.5

Notes: The parameters are listed, specifying the probabilities to commit to a specific neuron type (C_M–C₂, for MZ/layer 1 to layer 2) and the apoptotic probabilities at each stage (P_M–P₃, see Fig. 1). The final apoptotic probability P₂ fulfills the criterion P₂ + C₂ = 1 and so is not listed as a model parameter
