利用近红外光谱法(NIRS)，根据广义郎伯特-比尔定律（Lambert－Beer）可以实现活体脑血氧浓度的无创伤测量。在本论文中，通过将脑血氧饱和度和脑功能相结合的实验，讨论研究高级脑功能的可能性。利用事件相关实验可以检测脑的思维功能。实验结果的时域曲线差别不大。然而，利用DFT，五个被实验者的实验数据表明20Hz或40Hz频率的信号与困难的智力工作有关。实验结果表明了利用在频域范围内分析脑血氧饱和度的方法来进行脑功能研究的可行性。

With the use of Near-infrared spectroscopy(NIRS), the noninvasive measurement of cerebral oxygen concentration can be achieved in vivo based on the Lambert-Beer Law. In this paper, we discuss the possibility of studying higher brain functions through a combination of cerebral oxygen saturation and cerebral function measurement. Event-related experiments are introduced to measure the cerebral phronetal function. Time domain curves show sight differences among these experiment results. However, with the aid of DFT, experiment data of all five human volunteers show that the frequency near 20Hz or 40Hz is evoked depending on the difficulty of the mental tasks. The results demonstrate the feasibility of cerebral function studies by means of cerebral oxygen saturation measurement analysis in the frequency domain.
