Artistic Impression of Metabolism Based Chemotaxis

Our paper on A Minimal Model of Metabolism Based Chemotaxis has recently been published in PLoS Computational Biology.  In this paper, we connect Life and Mind by simulating metabolism-based behaviour.  More specifically, the concentration of a product of the metabolism directly modulates running/tumbling behaviour of simulated bacteria-like agents, producing a variety of sometimes surprising adaptive behaviours.

The simulation recreates phenomena observed in E. coli, A. brasilense and other bacteria and proposes explanations for previously unexplained observations, (such as the asymmetric distribution of bacteria in aerotaxis assays), demonstrating that the enactive / radically embodied / autopoiesis approach to cognition can contribute to our understanding of empirical data gathered from natural phenomena.
