GC reconstruction for a large network with low density connections.

<p>Illustrated here are results for a large IF network ( excitatory and inhibitory neurons) with random connectivity. The indices from to are for excitatory neurons and the indices from to are for inhibitory neurons. The total number of nonzero is (the percentage of connections is ) and the average neuronal firing rate is Hz. (A) The synaptic adjacency matrix with the white color indicating that and the black color for . (B) The absolute difference between and the causal adjacency matrix , i.e., . The white color indicates that , namely, and the black color for . By significance test (, See <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0087636#pone.0087636.s010" target="_blank">Text S1</a> for more details), the total number of is out of possible pairs of connections. Parameters are chosen as (Poisson input rate), (Poisson input strength), the coupling strength from excitatory to excitatory neuron and from excitatory to inhibitory neuron are (the corresponding EPSP is mV), whereas the coupling strength from inhibitory to excitatory neuron and from inhibitory to inhibitory neuron are (corresponding to IPSP mV).
