Ground truth connectivity and synaptic weights evolution. A Example connectivity matrix, all synapses present in the network were colored according to their communication delay. Absent synapses are grey. The red dashed lines separate the excitatory (N = 80 neurons) from the inhibitory (N = 20 neurons) population. B Ground-truth values of three example synaptic weights over time. Excitatory synapses (in orange and grey) evolved over time due to STDP, inhibitory synapses (in light blue) were constant over time. C Autocorrelation function of synaptic weights, the vertical dashed line indicates the autocorrelation half-life (64 s)
