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.

Animats in the Modelling Ecosystems (Response to Barbara Webb)

The Journal of Adaptive Behavior has recently published a target article by Barbara Webb entitled “Animats vs. Animals”. I was invited to write a critical response to her paper and joined Anthony Chemero to defend a variety of models in science, ranging from the most concrete to the most abstract.
