Influence of Neural Delay in Sensorimotor Systems on the Control Performance and Mechanism in Bicycle Riding

摘要

Neural sensorimotor systems have unavoidable delay in the processing. In this paper, we investigate the influence of the delay on its control performance and mechanism in numerical experiment with a simple network. The result suggests not only the fact that the delay degrades control performance of reflex motion in proportion to the amount of the delay, but also that the delay influences signal generation for relevant volitional motion. A moderate delay can even be in favor of volitional motion learning. The motion generation mechanism also seems dependent on the amount of delay. That is, a feedback strategy changes into a feedforward one with rough prediction.
