How Structure Determines Correlations in Neuronal Networks
Figure 9
Patches in separate populations selectively affect high-order common input motifs.
A: Connection rules for networks with patches. Output connections of a neuron are restricted to a randomly chosen region. B: Average correlations depending on patch size. Comparison between random networks, patchy networks with randomly distributed neuron type and separate populations, average across 5 networks, error bars from standard deviation. Only separate populations lead to increased correlations. Larger increase occurs for smaller patch-size. Total connection probability , other parameters as in Figure 2. C: Contributions of different motifs. Differences to random networks occur only in common input terms of higher order. Patch size
