... All excitatory synaptic weights were initially set to 0.05 and could vary between zero and 0.1 due to STDP. At the maximal weight, each spike would have a 50% probability of evoking a spike in the postsynaptic neuron, due to its summation with intrinsic noise (Figure S1-7). The synaptic weights for ...
