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

加州州立大学弗雷斯诺分校正在接受美国国家科学基金会的资助，将建立一个研究生物运动的3D运动工作室。这项研究将由大学教授乌尔里克·米勒指导。拟建的设施将包括五个数字高速相机，以前所未有的细节记录动物和植物的运动。绘制运动图对于发现推进系统、肌肉性能和控制特征以及理解综合行为(如捕食者-猎物相互作用)至关重要。该设施将用于研究飞虫、游鱼和吸力诱捕的肉食性水生植物。该设施将记录、跟踪生物体在三维空间中的位置和形状，并对其进行建模，例如鱼在转弯时如何弯曲。主要研究问题是：(1)生物体如何在转弯、跳跃、打斗、起跳或进食打击中为它们的运动提供动力和控制？(2)生物体的变化如何？S的结构特性和感官反馈影响控制和性能？3D运动工作室将是加州中部地区和一家西班牙裔服务机构的第一个此类设施。该设施是广泛的跨学科教学和研究活动的核心：它将为CSU弗雷斯诺分校生物、化学和计算机科学系的11个学生研究项目和每学期至少两门课程提供服务；它还将在国内和国际合作中为11名科学家提供服务。

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.
