| 摘 要： | 功能性近红外光谱技术（functional near-infrared spectroscopy, fNIRS）利用血液的主要成分对600-900nm近红外光良好的散射性，从而获得大脑活动时氧合血红蛋白和脱氧血红蛋白的变化情况。目前该技术开始运用于自然情境下的高级认知、发展心理学、异常心理学等多个领域的研究。该技术具有造价较低、便携性好，无噪音、无创性和对实验过程中被试动作不会过份敏感等优点，但也存在空间分辨率不高和校正算法有待进一步完善等方面的不足。未来fNIRS的研究可以与fMRI等其他成像技术进行结合，开展婴幼儿和特殊人群的认知神经科学研究以及自然情境下大脑认知的神经机制研究。

| Abstract: | Since the Neuroimaging techniques such as event-related brain potentials(ERPs) and functional magnetic resonance imaging (fMRI) are physically constraining,susceptible to motion artifacts and expensive,these traditional neuroimaging technologies do not meet the needs of researches on the young children,old people and disorders,and can't be used in the ecologicall setting.Functional near-infrared spectroscopy(fNIRS) is an emerging functional neuroimaging technology offering a relatively non-invasive,safte, p... |
