摘要
脑磁图不需要直接接触皮肤,是一种无损的记录大脑磁场信息的新技术,具有高灵敏度、高时间分辨率和高空间分辨率等特征,对于研究人脑工作机制有着至关重要的作用。作为一种超灵敏的室温磁强计,原子磁力计结构简单、建设廉价和维护成本低及适应性高,已经开始应用到脑磁的测量与研究中。文章介绍了脑磁图信号的发生机理、原子磁力计的原理,并阐明了原子磁力计在脑磁领域的研究现状,对其应用前景作出了展望。
Magnetoencephalography can record brain magnetic field information noninvasively without touching the skin.It is a new technology.It has the characteristics of high sensitivity,high temporal resolution and high spatial resolution.It plays an important role in studying the working mechanism of human brain.As an ultra-sensitive room temperature magnetometer,atomic magnetometer has been applied to the measurement and research of magnetoencephalography because of its simple structure,low construction cost,low maintenance cost and high adaptability.In this paper,the mechanism of magnetoencephalography signal generation and the principle of atomic magnetometer are introduced.The research status of atomic magnetometer in the field of magnetoencephalography is expounded,and its application prospect is prospected.
