A minimal model of metabolism-based chemotaxis

Egbert, M. D., Barandiaran, X. E., & Di Paolo, E. A. (2010). A Minimal Model of Metabolism-Based Chemotaxis. PLoS Comput Biol, 6(12), e1001004.

We present the first model of metabolism-based chemotaxis that accomplishes chemotaxis without transmembrane receptors or signal transduction proteins, through the direct modulation of flagellar rotation by metabolite concentrations. The minimal model recreates chemotactic patterns found in real bacteria, illuminating some previous work metabolism-dependent chemotaxis. A nice example of the inpiration taken from an autonomous perspective on agency, linking metabolism and behaviour.

Behavioral Metabolution: the very idea

The paper I wrote together with Matthew Egbert and Ezequiel Di Paolo got accepted and will be soon published at the Proceedings of the 12th International Conference on Artificial Life. It is entitled Behavioral Metabolution: Metabolism Based Behavior Enables New Forms of Adaptation and Evolution and it addresses, the evolutionary scale interaction between metabolism and behavior, using a simulation of a bacteria-like moving protocell whose behavioral architecture is constituted by metabolism itself.
