Spike information routing in the SSWD recurrent network model.
(a) A schematic illustration of the SSWD recurrent network. Thick lines stand for strong-sparse connections and thinner lines for weak-dense connections. In reality, the strength of connections is continuous obeying a long-tailed distribution. (b) Examples of spike sequences routed in the network are shown by different colors. Insets magnify the raster plot. (c) Examples of branching (left) and converging (right) pathways formed by the strong synapses. Numbers refer to neurons and colors to the corresponding pathways in (b). (d) Cross-correlograms are averaged over strongly connected neuron pairs (EPSP >8mV). (e) Repeated external stimuli (arrows) evoke simultaneous spike propagations in two pathways. (f) Linear relationship between the number of input spikes and that of output ones in a pathway. The dashed line and vertical bars represent linear regression and SD over trials, respectively.
