Brain activity is distributed over the 3-dimensional volume and evolves in time. Mapping dynamic brain activation with high spatial resolution and high temporal resolution is of great importance for understanding the brain functions and aiding in the clinical diagnosis and management of brain disorders. Electroencephalography (EEG) is a noninvasive technique to probe brain dynamics, and has been developed into a three-dimensional functional imaging modality for dynamic brain mapping. EEG has also played a significant role in our attempt to decode brain intention controlling a computer or device. This talk will consist of two parts: First, we will discuss the fundamental concepts of EEG and its relationship with the underlying brain activity, how EEG source imaging can offer a noninvasive window probing brain dynamics, and clinical applications to epilepsy source localization. Next, we will discuss the concepts and principles of EEG based brain-computer interface, and present our recent progresses in noninvasive brain-computer interface for controlling a virtual and physical object including flying a drone and controlling a robotic arm by “thought”. The presentation will feature the recent results from the group, and discuss challenges and opportunities of brain-computer interface, for aiding paralyzed patients as a medical technology, as well as the general population as a human-machine interface technology.
大脑的活动分布在三维空间中并随时间而演变。而绘制具有高空间分辨率和高时间分辨率的动态脑内活动成像,对于理解脑功能以及协助临床诊断和治疗大脑疾病具有重要的意义。脑电图(EEG)作为一种探测脑动态的无创性技术,已经发展成为用于脑动态图绘制的一种三维功能成像方法。EEG在我们试图解码大脑如何控制计算机或设备的过程中也起着重要的作用。本次讲座报告包括两个部分:首先,我们将讨论EEG的基本概念和它与潜在脑活动之间的关系,以及EEG源成像是如何实现无创非侵入式脑动态探测的。其次,我们也将会探讨基于EEG脑机接口的概念和原理,并介绍我们在用于控制虚拟和现实对象的无创脑机接口领域的最新研究进展,包括通过意识实现无人飞行器和机械臂的控制。本次讲座报告内容将会围绕着课题组最新的研究成果,讨论脑机接口所面临的机遇与挑战,以及作为辅助瘫痪病人的医疗技术和普通大众触手可及的人机接口技术。
