Acquisition of a High-Speed Video System for Motion Analysis

运动分析是理解基本生理过程的生物力学基础的关键。请求提供资金购买高速成像系统，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通过直接比较目前可用的前三个系统。选择的成像系统是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，可以以每秒500帧的速度以标准VHS格式拍摄43分钟，并具有直接模拟叠加。所有这些特征都是拟议研究所需的。 有待解决的问题包括：（1）系统发育的限制控制一个新的摄食系统在鱼类的进化？(2)温度对骨骼肌性能有什么影响？(3)化学感受在调节龙虾的刻板行为中扮演什么角色？(4)生物力学模型能用来检验功能性新事物的进化方向吗？(5)苍蝇翅膀运动的运动学分析能用来建立性格进化的模型吗？ 作为本研究主题的所有行为都以非常高的频率发生，超出了使用传统电影或视频的研究范围。此外，这些项目需要对复杂的三维运动进行分析，因此NAC HSV-500最能满足我们的需求。 大学提供了50%的配套资金，用于购买视频设备。

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.
