The problem of functional connectivity in the brain is in the focus of attention nowadays, since it is crucial for understanding information processing in the brain. A large repertoire of measures of connectivity have been devised, some of them being capable of estimating time-varying directed connectivity. Hence, there is a need for a dedicated software tool for visualizing the propagation of electrical activity in the brain. To this aim, the Trans3D application was developed. It is an open access tool based on widely available libraries and supporting both Windows XP/Vista/7(™), Linux and Mac environments. Trans3D can create animations of activity propagation between electrodes/sensors, which can be placed by the user on the scalp/cortex of a 3D model of the head. Various interactive graphic functions for manipulating and visualizing components of the 3D model and input data are available. An application of the Trans3D tool has helped to elucidate the dynamics of the phenomena of information processing in motor and cognitive tasks, which otherwise would have been very difficult to observe. Trans3D is available at: http://www.eeg.pl/.
目前，大脑功能连接性的问题是关注的焦点，因为它对于理解大脑中的信息处理至关重要。已经设计出了大量的连接性度量方法，其中一些方法能够估计时变的有向连接性。因此，需要一个专门的软件工具来可视化大脑中电活动的传播。为此，开发了 Trans3D 应用程序。它是一个基于广泛可用的库的开放访问工具，支持 Windows XP/Vista/7（™）、Linux 和 Mac 环境。Trans3D 可以创建电极/传感器之间活动传播的动画，用户可以将其放置在头部 3D 模型的头皮/皮层上。提供了各种用于操作和可视化 3D 模型和输入数据组件的交互式图形功能。Trans3D 工具的应用有助于阐明运动和认知任务中信息处理现象的动态，否则这些现象将非常难以观察。Trans3D 可在以下网址获取：http://www.eeg.pl/。
