|Issue Date:||16-Jul-2022||Date:||2022||Publication information:||Epilepsia 2022; 63(11)||Abstract:||Optically Pumped Magnetometers combined with Magnetoencephalography, or OPM-MEG, is an emerging and novel, cost-effective wearable system that can simultaneously record neuronal activity with high temporal resolution ('when' neuronal activity occurs) and spatial resolution ('where' neuronal activity occurs). This paper will first outline recent methodological advances of OPM-MEG compared to conventional SQUID-MEG before reasoning how OPM-MEG can become a valuable and non-invasive clinical support tool in epilepsy surgery evaluation. Although OPM-MEG and SQUID-MEG share similar data features, OPM-MEG is a wearable design that fits children and adults, and it is also robust to head motion within a magnetically shielded room. This means that OPM-MEG can potentially extend the application of MEG into the neurobiology of severe childhood epilepsies with intellectual disabilities (e.g., epileptic encephalopathies) without sedation. It is worth noting that most OPM-MEG sensors are heated, which may become an issue with large OPM sensor arrays (OPM-MEG currently has fewer sensors than SQUID-MEG). Future implementation of triaxial sensors may alleviate the need for large OPM sensor arrays. OPM-MEG designs allowing both awake and sleep recording are essential for potential long-term epilepsy monitoring.||URI:||https://ahro.austin.org.au/austinjspui/handle/1/30544||DOI:||10.1111/epi.17368||ORCID:||https://orcid.org/0000-0002-9199-1916
