脑磁图(MEG)通过评估神经元电活动产生的磁场来测量人脑功能。尽管提供了高质量的电生理活动的时空图,目前的MEG仪器是由繁琐的现场传感技术的限制,导致效用的主要障碍。在这里,我们回顾了新一代的MEG技术,开始解除许多这些障碍。通过利用量子传感器,称为光泵磁力计(OPM),“OPM-MEG”有可能大大超过目前的技术水平,有望提高数据质量(更好的灵敏度和空间分辨率),适应任何头部尺寸/形状(从婴儿到成人),运动鲁棒性(参与者可以在扫描过程中自由移动),以及不太复杂的成像平台(不依赖低温)。我们讨论了这一新兴技术的现状,并描述了其对神经科学的深远影响。
Magnetoencephalography (MEG) measures human brain function via assessment of the magnetic fields generated by electrical activity in neurons. Despite providing high-quality spatiotemporal maps of electrophysiological activity, current MEG instrumentation is limited by cumbersome field sensing technologies, resulting in major barriers to utility. Here, we review a new generation of MEG technology that is beginning to lift many of these barriers. By exploiting quantum sensors, known as optically pumped magnetometers (OPMs), ‘OPM-MEG’ has the potential to dramatically outperform the current state of the art, promising enhanced data quality (better sensitivity and spatial resolution), adaptability to any head size/shape (from babies to adults), motion robustness (participants can move freely during scanning), and a less complex imaging platform (without reliance on cryogenics). We discuss the current state of this emerging technique and describe its far-reaching implications for neuroscience.
