我们提出了一种新的探头设计，使同时脑电图（EEG）和近红外（NIR）光学成像的方式，这是很容易应用，允许最佳的两种形式的数据的配准，并最大限度地提高传感器的数量，可以应用到一个给定的区域。我们的探头设计评估使用双模态，组织模仿幻影，并通过执行一个简单的功能激活研究的人类运动皮层。我们成功地获得了近红外光学和脑电图数据，同时为我们的幻影和我们的人类运动皮层实验，清楚地表明了我们的“光电电极”的有效性和适用性。
We present a novel probe design which enables simultaneous electroencephalography (EEG) and near-infrared (NIR) optical imaging to be performed in a manner which is easy to apply, allows for optimum co-registration of the two forms of data and maximizes the number of sensors which can be applied to a given area. Our probe design is evaluated using a dual-modality, tissue-mimicking phantom and by performing a simple functional activation study of the human motor cortex. We successfully acquired NIR optical and EEG data simultaneously for both our phantom and our human motor cortex experiments, clearly demonstrating the effectiveness and suitability of our 'opto-electrode'.
