A neuromechanical model of the crayfish leg and thorax and the postural and locomotor circuitry built and run in AnimatLab v1. The model simulates experiments run with the BCI preparation model in which the model was linked in real time to the in vivo crayfish thoracic nerve cord. The model shows that current understanding of the neural circuitry can account for the increase in locomotor frequency when the sensori-motor feedback loop is intact.
Cell Type(s): Crayfish motor neuron
Transmitters: Acetylcholine
