Computing temporal sequences associated with dynamic patterns on the C. elegans connectome [article]

Vivek Kurien George, Francesca Puppo, Gabriel A Silva
2020 bioRxiv   pre-print
To study network signaling pathways responsible for the dynamics we developed an analytic framework that constructs Temporal Sequences (TSeq), time- ordered walks of signals on graphs.  ...  We simulated the plausible dynamics resulting from the known C. elegans connectome using a recent model and theoretical analysis that computes the dynamics of neurobiological networks by focusing on how  ...  In this work we introduce a novel set of methods and analyses for this task, and apply it to the dynamics of the Caenorhabditis elegans worm connectome as an example.  ...

Ruddi Rodriguez Garcia, Laurent Chesneau, Sylvain Pastezeur, Julien Roul, Marc Tramier, Jacques Pécréaux
2017 arXiv   pre-print
Importantly, this mechanism, which modestly accounts for cortical forces, does not transport dynein, which displays the same binding/unbinding dynamics as EBP-2^EB1.  ...  Their densities are higher on the posterior tip of the embryos, where GPR-1/2^LGN concentrate, but their durations are symmetric.  ...  The MosSci strain was made by the UMS 3421 Biology of Caenorhabditis elegans facility, CNRS/UCBL (Lyon, France).  ...
