In the burrowing cockroach Arenivaga, two giant interneurons in each connective of the ventral nerve cord provide gravity orientation information. The interneurons receive input from plumb bob-like equilibrium receptors on the ventral surface of the cerci. Ouir results support the theory that the cerci of cockroaches are specialized equilibrium organs.
