Dynamic information routing in Caenorhabditis elegans

Abstract

aenorhabditis elegans (c. elegans) is a transparent nematode of about 1 mm of length. As of 2021, it is the only organism whose connectome, i.e. the neuronal connectivity diagram, has been fully tracked. Thus, it conforms the most realistic example of a biological neural network. In a context of homogeneous frequencies, signals applied to a frequency-boosted neuron lead to a process of harmonics generation within the network. The quality of their propagation is highly dependent on the response of the senders and the sender-receiver relative phases. Lastly, the network structure seems to restrict information spreading in structural hubs in favor of nodes with lower out-degree, when compared to degree-preserved randomizations. Furthermore, the effect of the topology qualitatively differs depending on the neuron type.
