摘要
苍蝇以其杂技般的机动性而闻名,例如,它们可以以超过3000度/秒的转弯速度追逐伴侣,延迟时间不到30毫秒(Land and Collett 1974;瓦格纳1986 a, b, c)。正是这种奇妙的行为引发了许多关于其感官控制以及飞行输出的生物物理和空气动力学原理的研究(Dickinson et al. 1999Dickinson et al. 2000)。特别是,苍蝇作为一种模式生物,导致了用于基本运动检测的Reichardt模型的发展,这是迄今为止计算神经科学中最具影响力和最成功的模型之一。在这里,我们回顾了目前关于光流的神经处理的知识状态,它代表了一个与飞行控制密切相关的感觉成分。除非另有说明,否则下列所有数据均来自我们通常随意称之为“苍蝇”的绿头苍蝇Calliphora vicina。苍蝇的视觉系统视觉运动的处理始于眼睛。苍蝇和大多数无脊椎动物一样,这种结构是由许多称为面或小孔的单一元素构成的。每个小眼都有自己的小晶状体和自己的一套感光器。后者将轴突送入大脑中专门负责图像处理的部分,称为“视觉神经节”。在果蝇中,视神经节由连续的三层神经堆组成,其中柱状结构反映了眼内小平面的相对位置。因此,被感知的视觉图像…
Flies are known for their acrobatic maneuverability which enables them, for example, to chase mates at turning velocities of more than 3000 deg/sec with delay times of less than 30 msec (Land and Collett 1974; Wagner 1986a,b,c). It is this fantastic behavior that has initiated much research both on its sensory control and on the biophysical and aerodynamic principles of the flight output (Dickinson et al. 1999Dickinson et al. 2000). In particular, the fly served as one of the model organisms leading to the development of the Reichardt model for elementary motion detection, one of the most influential and successful models in computational neuroscience up until today. Here, we review the current state of knowledge about the neural processing of optic flow that represents one sensory component intimately involved in flight control. Unless stated otherwise, all data presented in the following were obtained on the blowfly Calliphora vicina , which we will often casually refer to as “the fly.” THE FLY VISUAL SYSTEM The processing of visual motion starts in the eye. In flies, as in most invertebrates, this structure is built from many single elements called facets or ommatidia. Each ommatidium possesses its own little lens and its own set of photoreceptors.
