Before revision:  While these networks provide global connectivity and sustain the broad spectrum of the functions of the brain, the underlying routing strategies for communication between the different areas and their control remain to be elucidated. Here, we investigate the flow of information in connectomes of several species using greedy routing as a distributed navigation protocol .
After revision:  Using a decentralized navigation protocol, we investigate the relationship between the structure of the connectomes of different species and their spatial layout. As a navigation strategy, we use greedy routing where nearest neighbors, in terms of geometric distance, are visited. We measure the fraction of successful greedy paths and their length as compared to shortest paths in the topology of connectomes .
