Abstract: Optically pumped magnetometers (OPM) use gaseous atoms as sensitive magnetic field probes. Thus, the quantum mechanical state of atoms is prepared with laser light and the effect of a magnetic field is read out with laser light. OPMs have developed rapidly over the last ten years and now achieve similar sensitivities to conventional SQUID-MEG systems. Accordingly, OPMs could be an important technology for brain imaging and have the potential to provide new insights into psychiatric syndromes, such as schizophrenia. In my talk, I will present recent studies investigating the signal-to-noise ratio (SNR) characteristics of OPM data compared to conventional EEG and SQUID-MEG measurements. Furthermore, results in patients with schizophrenia suggest that OPMs may provide insights into altered neuronal oscillations.
