Talk of  Nathalie Rhodes on October 5th at 4pm:

Title: Towards a wearable whole-head paediatric MEG system with OPMs

Abstract: Lightweight and flexible OPMs have brought about a new era of MEG, free from cumbersome cryogenically cooled technologies. In this talk, I will present the development of OPM-MEG at Nottingham over the past 6 years, from single channel recordings in 2017; whole-head measurements in adults in 2020; and now triaxial systems, recording almost 200 channels of MEG data. I will then focus on my PhD research, which has been working towards a paediatric OPM-MEG system. I will discuss the technical challenges of paediatric recordings, including movement artefact and low frequency sensitivity, presenting results from my comparison paper with conventional MEG across the theta-band. I will share new results from our first neurodevelopmental study, where we looked at age-related changes in spectral content during a sensory task with 27 children aged 2 – 13 years old and 26 adults aged 21-34. Finally, I will present results from our collaboration with SickKids hospital in Toronto, including efforts to collate large datasets cross-site.
