Modeling And Simulation Of Caenorhabditis elegans Chemotaxis In Response To A Dynamic Engineered Bacteria

2015 ECMS 2015 Proceedings edited by: Valeri M. Mladenov, Petia Georgieva, Grisha Spasov, Galidiya Petrova  
Through the model we observe that, under static conditions, the diffusion rate of the chemoattractant is critical in influencing choice of C. elegans.  ...  We then show that if the worms learn that the chemoattractant is associated with toxicity, choice index is counterintuitively more strongly reduced with increasing diffusion rate.  ...  We would like to thanks Olena Bracho and Cyril Manchery for providing unpublished data and discussions on the experimental framework.  ...
