Octopuses have soft and flexible bodies and their behavior is extremely sophisticated. Their behavioral control is accomplished using a simplification strategy, which is based on the division of functionality between the central and peripheral nervous systems. The behavioral control is simplified since the central nervous system only sends the initiation commands to the peripheral nervous system. While the timing to send the command is crucial. In this study, we aim to characterize the relationship between them using a simulated octopus arm. As a result, we show that there exists a clear behavior difference according to the time it takes to initiate the behavior, which may suggest that the behavioral outcome is determined in the early phase of motion generation.
