可控的、动态的感觉刺激的呈现提供了一个强大的实验范式，它已被广泛应用于探索行走和系留飞行昆虫的感觉加工。计算机硬件和软件技术的最新进展提供了跟踪自由飞行昆虫的3D飞行路径并实时处理这些数据的机会，为向自由飞行动物提供动态刺激提供了可能性。为了适应与3D空间相关的增加的复杂性，我们划分了实验设计。实时数据采集和激励控制集成到多个独立模块中。通过锻造多个3D空间刺激关系，在独立应用程序中创建3D实验场景。动态线索的使用说明了一个实验，其中动态的声学线索提出了一个自由飞行的寄生蝇在一个大的三维环境。松散耦合模块的组合提供了强大而灵活的解决方案。允许基于现有技术容易地实现新的范例。我们证明了这一点，显示一个复杂的视觉刺激，实时控制的测试对象的2D位置和方向的测试系统。所提出的方法适用于各种新的实验范式，包括学习范式，在步行游泳和飞行动物的各种感觉方式。(C)2004 Elsevier B.V保留所有权利。
The presentation of controllable, dynamic sensory stimuli provides a powerful experimental paradigm, which has been extensively applied to explore sensory processing in walking and tethered flying insects. Recent advances in computer hardware and software technology provide the opportunity to track the 3D flight path of free-flying insects and process these data in real-time, opening up the possibility to present dynamic Stimuli to free-flying animals. To accommodate for the increased complexity relating to 3D space, we partitioned experimental design. real-time data acquisition and stimulus control into multiple self-contained modules. 3D experimental scenarios were created in a stand-alone application by forging multiple 3D space-stimulus relationships. The use of dynamic cues is illustrated by an experiment, in which dynamic acoustic cues were presented to a free-flying parasitoid fly in a large 3D environment. The combination of loosely coupled modules provides robust and flexible solutions. allowing new paradigms to be readily implemented based on existing technologies. We demonstrate this with a test system that displayed a complex visual stimulus, controlled in real-time by the 2D position and orientation of a test object. The presented methods are applicable in a variety of novel experimental paradigms, including learning paradigms, for various sensory modalities in walking swiming and flying animals.
