Despite providing high quality spatiotemporal maps of electrophysiological activity, current instrumentation for magnetoencephalography (MEG) is limited by cumbersome field sensing technologies, resulting in major barriers to utility. In this talk I will discuss 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 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). I will discuss the current state of this emerging technique and describe its far-reaching implications for neuroscience.
