Synapse density. The upper row gives results for NETMORPH and the bottom row for CX3D. The curves mark the mean values, and the bars show the standard deviations. (a) shows the mean number of synapses per neuron when the elongation rate for basal dendrites takes values 1, 2, 4, 6, and 8 μm/day. (b) shows the magnified region of interest from (a), that is, the interval between 7 and 14 developmental days. The "*" mark the experimental values for the corresponding days, taken from [21]. (c) shows the synapse density obtained using CX3D, and the elongation rates for basal dendrites equal to 2, 6, 10, 14, and 22 μm/day. The experimental data (*) correspond well to the values obtained for μm/day.
