MRI: Acquisition of a High-speed Camera System to Record Animal Movements in Three Dimensions

位于弗雷斯诺的加州州立大学正在接受美国国家科学基金会的资助，建立一个3d运动工作室来研究生物运动。这项研究将由大学教授Ulrike m<e:1> ller指导。拟建的设施将包括5台数码高速摄像机，以前所未有的细节记录动植物的运动。运动映射对于发现推进系统、肌肉表现和控制特征以及理解捕食者-猎物相互作用等综合行为至关重要。该设施将用于研究飞虫、游泳鱼和吸力捕食性水生植物。该设备将在三维空间中记录、跟踪和模拟生物体的位置和形状，例如鱼在转弯时如何弯曲。主要的研究问题是：(1)生物如何在转弯、跳跃、战斗、起飞或捕食时控制它们的运动？(2)机体的变化是怎样的？结构特性和感觉反馈影响控制和性能？这家3d动画工作室将是加州中部地区第一家这样的机构，也是一家为西班牙裔服务的机构。该设施是广泛的跨学科教学和研究活动的核心：它将为11个学生研究项目提供服务，并为科罗拉多州立大学弗雷斯诺分校生物、化学和计算机科学系每学期至少开设两门课程；它还将为11名科学家提供国内和国际合作。

California State University at Fresno is recieving funding from the National Science Foundation for a 3D-motion studio to study bio-locomotion. The research will be directed by University Professor Ulrike Müller. The proposed facility will comprise five digital high-speed cameras to record animal and plant motion in unprecedented detail. Mapping motion is vital to discovering propulsion systems, muscle performance, and control features along with understanding integrative behaviors such as predator-prey interactions. The facility will be employed to study flying insects, swimming fish and suction-trapping carnivorous water plants. The facility will record, track and model the position and shape of an organism in three-dimensional space, e.g. how fish bend while turning. The main research questions are: (1) How do organisms power and control their motion during turns, leaps, fights, take-offs, or feeding strikes? (2) How do changes in the organism?s structural properties and sensory feedback affect control and performance?The 3D-motion studio will be the first such facility in the Central California region and at a Hispanic-serving institution. The facility is at the heart of a wide range of cross-disciplinary teaching and research activities: it will serve 11 student research projects and at least two courses each semester in the Departments of Biology, Chemistry and Computer Science at CSU Fresno; it will also serve 11 scientists in national and international collaborations.
