NISHIKAWA 9809942 As functional morphologists and neurobiologists, the PIs wish to predict how patterns of muscle activation should change, not only when an individual performs different tasks but also during its lifetime as it grows, and as body proportions change during evolution. These tasks are currently beyond the PIs reach because patterns of muscle activation are affected by a large number of factors, including the contractile properties of the muscles, their mechanical advantage, the masses and lengths of the segments, and the force, velocity and duration of movement. Unraveling the complexity of muscle activation is an important basic problem of organismal biology. The goal of the proposed research is to develop prey capture in frogs as a model system for investigating this problem. In this proposal, the PIs seek funds to develop biornechanical models that will predict how body size and morphological evolution affect patterns of muscle activation; and for empirical studies that will be used to modify the models and test their predictions. These studies will contribute significantly to the development of a theoretical framework in which the effects of body size and morphological evolution on patterns of muscle activation can be predicted and ultimately tested.

Nishikawa 9809942作为功能形态学家和神经生物学家，PIS希望预测肌肉激活的模式应该如何改变，不仅是当一个人执行不同的任务，而且随着其生长的生长以及身体比例在进化过程中的变化时也会改变。这些任务当前超出了PI的范围，因为肌肉激活的模式受大量因素的影响，包括肌肉的收缩特性，其机械优势，段的质量和长度以及力，速度和运动的持续时间。阐明肌肉激活的复杂性是生物学的重要基本问题。拟议的研究的目的是开发青蛙中的猎物捕获，作为研究此问题的模型系统。在此提案中，PI寻求资金开发生物力学模型，以预测体大小和形态进化如何影响肌肉激活的模式。 以及将用于修改模型并测试其预测的经验研究。这些研究将对理论框架的发展产生重大贡献，在这种框架中，可以预测并最终测试身体大小和形态进化对肌肉激活模式的影响。
