The analysis of motion is crucial in understanding the biomechanical basis of fundamental physiological processes. Funds are requested to purchase a high-speed imaging system that will allow the quantitative analysis of the musculoskeletal system in both vertebrates and invertebrates. The criteria for selection of a high-speed imaging system is followed by the direct comparison of the top three systems currently available. The imaging system chosen is the NAC HSV-SOOHSG. This video system can operate in low light conditions, has dual camera capabilities, can film at rates up to 500 frames per second in standard VHS format for 43 minutes, and has direct analog overlay. All these features are required for the proposed research. Questions to be addressed include: (1) Are phylogenetic constraints controlling the evolution of a novel feeding system in fish? (2) What is the effect of temperature on skeletal muscle performance? (3) What role does chemoreception play in the modulation of a stereotypical behavior in lobsters? (4) Can biomechanical models be used to test the direction of evolution in functional novelties? (5) Can kinematic analysis of wing movement in flies be used to generate models of character evolution? All behaviors that are the subject of this research occur at very high frequency and are beyond the scope of study using conventional film or video. Furthermore, these projects require the analysis of complex movements in three dimensions, thus, the NAC HSV-500 best meets our needs. A university contribution of 50% matching funds towards the purchase of the video equipment has been provided.

运动分析对于理解基本生理过程的生物力学基础至关重要。申请资金用于购买高速成像系统，以便对脊椎动物和无脊椎动物的肌肉骨骼系统进行定量分析。选择高速成像系统的标准是直接比较目前可用的前三种系统。成像系统选用NAC HSV-SOOHSG。该视频系统可以在弱光条件下工作，具有双摄像头功能，可以以标准VHS格式以每秒500帧的速率拍摄43分钟，并具有直接模拟覆盖。所有这些特征都是本研究所需要的。需要解决的问题包括：(1)系统发育限制是否控制了鱼类新摄食系统的进化？(2)温度对骨骼肌性能有什么影响？(3)化学感受在龙虾刻板行为的调节中起什么作用？(4)生物力学模型能否用于测试功能创新的进化方向？(5)苍蝇翅膀运动的运动学分析能否用于生成性格演化模型？所有作为本研究主题的行为都以非常高的频率发生，并且超出了使用传统电影或视频研究的范围。此外，这些项目需要在三维空间中分析复杂的运动，因此NAC HSV-500最能满足我们的需求。大学为购买视频设备提供了50%的配套资金。
