ABSTRACT We demonstrated that a controlled locomotory response in American cockroaches (Periplaneta americana L,) can be elicited using an electrical stimulation directed toward the thoracic ganglia. This was done on a tracking apparatus where the cockroach’s walking trajectory corresponding to electrical signal was recorded. Walk and turn initiation was achieved by directly stimulating the lateral regions of the prothoracic ganglion. We characterized the turning behavior and endurance to stimulation which were evaluated against the input parameters such as voltage and frequency. It was found that the frequency had a more dominant role in steering a roach than the input voltage. The response endurance can be significantly enhanced by giving consecutive stimulation at proper time intervals.
