近红外光谱是一种非侵入性神经成像方法,它利用光来测量与大脑活动相关的脑血氧变化。在这项工作中,我们展示了使用16通道连续波光学近红外系统实时记录和分析大脑活动图像的能力。我们提出了一种新的实时分析框架,使用自适应卡尔曼滤波器和基于典型一般线性大脑活动模型的状态空间模型。我们表明,我们的自适应模型有能力估计单次大脑活动事件,因为我们应用这种方法来跟踪和分类在交替的双侧自节奏手指敲击任务中获得的实验数据。
Near-infrared spectroscopy is a non-invasive neuroimaging method which uses light to measure changes in cerebral blood oxygenation associated with brain activity. In this work, we demonstrate the ability to record and analyze images of brain activity in real-time using a 16-channel continuous wave optical NIRS system. We propose a novel real-time analysis framework using an adaptive Kalman filter and a state–space model based on a canonical general linear model of brain activity. We show that our adaptive model has the ability to estimate single-trial brain activity events as we apply this method to track and classify experimental data acquired during an alternating bilateral self-paced finger tapping task.
