Abstract: Magnetoencephalography (MEG) is a reliable non-invasive brain imaging technology that was invented over 50 years ago and is now used both clinically and in neuroscience research. Optically pumped magnetometers (OPMs) are an emerging sensor technology that promises to transform MEG through greater motion tolerance and adaptability to different head sizes, ushering in a new generation of wearable MEG systems. In this talk, he will discuss some of the technical innovations that are enabling this transition, with a focus on their use in young children. I will compare OPMs with conventional MEG and highlight the challenges and opportunities ahead.
Bio: Dr. Mainak Jas is an Instructor of Radiology at the David Cohen MEG Laboratory in Massachusetts General Hospital (MGH). His NIH-funded research focuses on developing and applying wearable magnetoencephalography (MEG) in healthy children and children with epilepsy. Prior to joining MGH, he completed his PhD at Telecom ParisTech in Signal and Image Processing applied to multivariate neural time series. He has co-developed MNE-Python and Autoreject, which are widely used open-source tools for MEG data analysis.
