Abstract(in English) | Motor control depends on modalities with different latencies. In this paper, we consider how to combine different sensory modalities for real-time optimal movement. We suggest that the modality with shorter latency should have an advantage. We demonstrate with an example simulation of a visuomotor sequence reaching task. In our example, the behaviour is initially a visually guided, point-to-point movement. By learning, the sensorimotor modality gradually gains influence, and the movement became faster and optimized to the full sequence. After learning, the sensorimotor modality were dominant in executing the sequence, while the visual module still played a vital part when the arm lost control of the execution. We found that the shorter the relative latency of the sensorimotor modality, the more influential it became of the acquired skill. |
