摘要

神经元如何检测运动方向是神经计算的一个主要例子:运动视觉存在于几乎所有有视力的动物的视觉系统中,它对生存很重要,它需要有趣的计算和定义良好的线性和非线性处理步骤,但整个过程的复杂性适中。果蝇的遗传方法及其视觉系统连接组的绘制,使我们对神经元如何计算这种生物的运动方向的理解取得了快速进展和前所未有的细节。出现的图像不仅包含了每个神经元的身份、形态和突触连通性,还包含了它的神经递质、受体和它们的亚细胞定位。再加上神经元对视觉刺激的膜电位反应,这些信息为计算视觉运动方向的电路的生物物理现实模型提供了基础。

How Flies See Motion.

How neurons detect the direction of motion is a prime example of neural computation: Motion vision is found in the visual systems of virtually all sighted animals, it is important for survival, and it requires interesting computations with well-defined linear and nonlinear processing steps-yet the whole process is of moderate complexity. The genetic methods available in the fruit fly Drosophila and the charting of a connectome of its visual system have led to rapid progress and unprecedented detail in our understanding of how neurons compute the direction of motion in this organism. The picture that emerged incorporates not only the identity, morphology, and synaptic connectivity of each neuron involved but also its neurotransmitters, its receptors, and their subcellular localization. Together with the neurons' membrane potential responses to visual stimulation, this information provides the basis for a biophysically realistic model of the circuit that computes the direction of visual motion.

期刊介绍: The Annual Review of Neuroscience is a well-established and comprehensive journal in the field of neuroscience, with a rich history and a commitment to open access and scholarly communication. The journal has been in publication since 1978, providing a long-standing source of authoritative reviews in neuroscience. The Annual Review of Neuroscience encompasses a wide range of topics within neuroscience, including but not limited to: Molecular and cellular neuroscience, Neurogenetics, Developmental neuroscience, Neural plasticity and repair, Systems neuroscience, Cognitive neuroscience, Behavioral neuroscience, Neurobiology of disease. Occasionally, the journal also features reviews on the history of neuroscience and ethical considerations within the field.
