摘要
Functional brain imaging technology has developed rapidly in recent years.On the one hand,high-field 7-Tesla magnetic resonance imaging(MRI)has excelled the limited spatial resolution of 3-Tesla MRI,allowing us to enter a new world of mesoscopic imaging from the macroscopic imaging of human brain functions.On the other hand,novel optical pumping magnetometer-magnetoencephalography(OPM-MEG)has broken down the technical barriers of traditional superconducting MEG,which brings imaging of neuronal electromagnetic signals from cortical imaging to whole-brain imaging.This article aims to present a brief introduction regarding the development of conventional MRI and MEG technology,and,more importantly,to delineate that high-field MRI and OPM-MEG complement each other and together will lead us into a new era of functional brain imaging.
