Abstract

We have approached the problem of translating sensory information to a coordinated pattern of muscular activation by designing a neuronal model for the initial positioning of the cat's hindlimb and its rhythmic behavior in the scratch reflex. The scratch reflex is a behavior where tactile stimulation on the neck region of a spinalized cat will lead to a two phase response. Initially, the animal positions the hindlimb so that it's paw can reach the irritation site (positioning phase). This is then followed by an oscillatory wiping motion (rhythmic phase). Since the spinal circuitry is capable of producing these complex motor patterns, it is held that a neural network residing wholly in the spinal cord must exist that contains all the necessary details for control of this reflex. Understanding the mechanism, by which the animal maps the site of irritation on the skin onto a neuronal circuitry that is capable of generating a temporal pattern of muscular activation, can be beneficial for engineering a system in which spatial input is transformed to a coordinated motor output.
