「From Homeostasis to Sensory Motor Couplings」
We know how sensory-motor couplings can simulate primitive but a variety of cognitive behaviors. But the origin of sensory-motor coupling itself is remained as an open question. We tackle this problem by re-visiting the problem of the origin of life forms both theoretically and experimentally. I insist that dynamic homeostasis is the key notion that bridges the gap between self-preservation and sensory-motor coupling.
Autopoiesis theory tells us that life form emerges when a spatial region generates a self-boundary and starts to maintain by itself. My first talk is to introduce a simple chemical experiment of an oil droplet that generates a surfactant boundary and showing self-motility with it.
In order to see how homeostatic behavior leads to sensory-motor couplings theoretically, we generalized Inman Harvey's simple Daisy World agent to explore the world. The agent's surface is covered with two kinds of daisies that cooperatively adjust the surface temperature. We showed how the agent can maintain the surface temperature constant irrespective of the environmental temperature and how explorative behavior can be generated at the same time.
My simulation experiment showed that the homeostatic state is maintained by "Homeochaos" and a partially ordered chaotic state can generate a coherent and explorative movement in the inhomogeneous environment. This is going to be my second talk.
