Information processing in axons has attracted attention for potential application in the control of soft robots. In this letter, we present the evaluation of axon conduction properties in cultured sensory neurons. Distal axons showed latency oscillations in response to high-frequency stimulation, thereby suggesting the suitability of our method for evaluating the information processing function of axons. Understanding axon information processing has a potential to contribute to the development of an advanced control method for soft robots.
