中文简介: | 近红外光谱(NIRS)非侵入性地测量脑内局灶性神经元活动后的血流动力学变化。NIRS以可移动、不引人注目和经济的方式提供新皮质功能成像,有望对未来BCI应用产生重大影响。在本课程中,我们将介绍NIRS的原理,即测量的生物学和物理背景、仪器以及BCI领域的一些最新应用。在实验课程中,我们将解释NIRS扫描仪的原理,并演示其使用和典型实验装置的准备。我们将进行一项生理学实验,测量由执行和假想的手抓握引起的血流动力学变化。然后,将使用常用于近红外信号的方法对实验结果进行分析 |
课程简介: | Near-Infrared Spectroscopy (NIRS) measures the hemodynamic changes following focal neuronal activity in the brain non-invasively. NIRS affords imaging of neocortical functions in a mobile, unobtrusive, and economical way, promising a high impact on future BCI applications. In this session we will introduce the principles of NIRS, i.e. the biological and physical background of the measurement, its instrumentation, and some recent applications in the field of BCI. In the experimental session we will explain the principles of a NIRS scanner and demonstrate its use and the preparation of a typical experimental setup. We will perform a physiological experiment of measuring the hemodynamic changes caused by executed and imaginary hand-gripping. The experimental results will then be analyzed using methods commonly applied to NIRS signals |
