Models for the generation of the motor output pattern in flying locusts

The motor output to the flight muscles of flying locusts is described briefly. Model neural networks that simulate many aspects of this output pattern are discussed. The model networks studied consisted of interconnected electronic analogs of unit patches of neural membrane. The analog units were designed by E. R. Lewis. The simplest network model, which we believe simulates the locust flight-control system reasonably well, consists of two groups of elements. The members of each group are mutually excitatory and produce bursts of impulses separated by rest periods. The two groups inhibit each other so that their bursts of activity alternate.
