Description
The goal for this study is to compare performance between a conventional helium based “Cryo_MEG” (magnetoencephalography) system and an investigational optically pumped (‘OP_MEG’) MEG system using brain recordings from typically developing adults. MEG (magnetoencephalography) is a safe, non-invasive brain imaging method used in many forms of research as well as clinical care. MEG is measured by safely wearing a helmet filled with MEG sensors. During the MEG scan, you will be asked to look at a screen, listen to some tones, and push a button. OPM (Optically Pumped Magnetometry), is a brain imaging method that is also worn as a helmet and acquires MEG recording data but differs from conventional “cryo-MEG” because OPM sensors can be positioned closer to the head. This may present an opportunity for better measurement of underlying brain activity.
What to expect
The study will involve one visit to The Childrenâs Hospital of Philadelphia. During the visit, participants will undergo a cryo-MEG scan as well as an OP_MEG scan, where four experiments will be performed on each of the two MEG modalities for a total of 1.5 hours. This is followed by a brain MRI scan as the final part of the visit.Â
