AbSTRACT
Computational neuroscience has a lot to gain from invertebrate research. In this chapter focusing on
the sensory-motor network that controls leg movement and position in crayfish, we describe how simple
neural circuitry can integrate variable information to produce an adapted output function. We describe
how a specific sensor encodes the dynamic and static parameters of leg movements, and how the central
motor network assimilates and reacts to this information. We then present an overview of the regula-
tory mechanisms thus far described that operate at the various levels of this sensory-motor network to
organize and maintain the system into a dynamic range. On the basis of this simple animal model, some
basic neurobiological concepts are presented which may provide new insights for engineering artificial
autonomous systems.
