Synthetic Approaches to Neurobiology: Review and Case Study in the Control of Anguiliform Locomotion

. This paper briefly reviews synthetic approaches to neurobiology and presents results of two experiments on the use of evolutionary algorithms for the design of neural controllers for locomotion. The first experiment consists in using the evolutionary algorithm for instantiating low level parameters of a connectionist simulation of the lamprey's locomotor circuitry. The second experiment develops potential neural circuits for the swimming and trotting of the salamander; an animal whose locomotor circuitry has currently not been decoded. In both cases, biologically plausible control circuits are developed which produce a neural activity with many similarities to that measured in the real animals. 1 Synthetic approaches to neurobiology The fields of artificial life and artificial intelligence have developed tools and methods which have the potential to significantly help computational neurobiology. Synthetic approaches to neurobiology can indeed increase our understanding of ..
