Abstract: We investigated a parsimonious structured network with common inputs and spiking non-linearities. Unlike a homogeneous network, a network with heterogeneous connections can provide not only a tuning curve of firing rates but also a relationship among the statistics gathered from neurophysiological experiments in the primary visual cortex. We found that the heterogeneous structure of the network can dynamically control the structure of 3rd-order correlations and can generate both sparse and synchronized neural activity, and proposed a decisive experiment to test the effect of inhomogeneous connectivity on higher-order correlations. These theoretical results indicate that the 3rd-order correlations resulting from visual stimulation can carry stimulus-specific information.
