神经网络的“发展”方法（将实验研究与计算建模相结合）的最新进展产生了越来越大的数据集，无论是复杂性还是大小。这对分析、可视化和理解这些网络的空间结构和行为提出了重大挑战。本文描述了一个虚拟现实应用程序，用于可视化两个生物学上精确的计算模型，该模型模拟了由1500个神经元和超过80，000个连接组成的神经网络的解剖结构。可视化使用户能够观察七种独特类型的神经元之间复杂的时空相互作用，最终形成可观察到的游泳模式。我们提出了一个虚拟环境的设计方法的详细描述，根据一组初始要求，随后的实施和优化步骤。最后，一项试点可用性研究的结果正在介绍参与者对他们理解蝌蚪身体两侧之间的交替发射模式如何产生游泳运动的能力有多有信心。
Recent advances in “developmental” approach (combining experimental study with computational modeling) of neural networks produce increasingly large data sets, in both complexity and size. This poses a significant challenge in analyzing, visualizing and understanding not only the spatial structure but also the behavior of such networks. This paper describes a virtual reality application for visualization of two biologically accurate computational models that model the anatomical structure of a neural network comprised of 1500 neurons and over 80,000 connections. The visualization enables a user to observe the complex spatiotemporal interplay between seven unique types of neurons culminating in an observable swimming pattern. We present a detailed description of the design approach for the virtual environment, based on a set of initial requirements, followed up by the implementation and optimization steps. Lastly, the results of a pilot usability study are being presented on how confident participants are in their ability to understand how the alternating firing pattern between the two sides of the tadpole’s body generates swimming motion.
