    "abstract": "How does network topology affect neural coding? We approached this question with a large parametric study\nsimulating clustered network topologies of cortical excitatory spiking neurons with inhibitory interneurons, while taking into\naccount variance in axonal length and spike propagation times. To evaluate the stability of rate coded information, we systematically\nvaried within cluster conduction delay means, variances, and connection densities, as well as between cluster conduction\ndelay means, variances, and connection densities. Networks received rate coded stimulation from one cluster, and we varied\nfrequency and spike jitter of this input. Networks contained 960 excitatory and 240 inhibitory neurons, divided evenly between\n6 recurrently connected clusters. We found that variances of inter-spike intervals in the presence of rate coded stimulation\nwere greatly increased with the introduction of even small variances in between cluster conduction delays and by changes in\ninter-cluster and within-cluster connection density, identifying topologies that resist stable rate coding.",
