We presently lack a broad comparative understanding of the neuromuscular basis of lower vertebrate locomotor behavior. Notably, no previous study has quantitatively measured axial muscle activity in salamanders which are the most primitive extant tetrapodal vertebrates. The proposed research on fish and salamander locomotor behavior will simultaneously examine axial movements and the underlying patterns of muscle activity (the motor pattern). By comparing taxa with different shapes, numbers of body segments and limbed versus limbless animals, the influence of morphology on motor pattern will be assessed. By altering viscosity and determining the motor pattern for terrestrial and aquatic locomotion, the influence of the environment on the motor pattern will be determined. Comparisons of axial motor patterns over a wide range of speeds, taxa, and environmental conditions will allow examination of the plasticity of neural control in locomotor behaviors.

我们目前缺乏对这一问题的广泛比较了解。 低等脊椎动物运动行为的神经肌肉基础。 值得注意的是，以前没有研究定量测量轴向 蝾螈最原始的肌肉活动 现存的四足脊椎动物。 关于鱼类的研究， 蝾螈的运动行为将同时检查轴向 运动和肌肉活动的基本模式（ 运动模式）。 通过比较不同形状、数量的分类群 有肢动物和无肢动物的身体片段， 将评估形态学对运动模式的影响。 通过 改变粘度并确定运动模式， 陆地和水生运动， 环境对运动模式的影响将被确定。 比较 轴向电机模式在很宽的速度范围内，类群， 环境条件将允许检查塑性 运动行为的神经控制。
