| Summary | Background: Brain activity produces magnetic fields. These fields can be measured outside the head. Existing technology, called MEG, measures these fields. Researchers are testing a new type of magnetic field sensor called OPM. They hope it can help pinpoint with very high accuracy where brain activity is generated. Objective: To develop and test a new type of sensor for measuring the magnetic fields produced by brain activity. Eligibility: Healthy people ages 18-65 who had a magnetic resonance imaging (MRI) scan under protocol 17-M-0181. Design: Participants may be asked to complete sessions on both the traditional MEG instrument and the OPM array. For the MEG, 3 small coils will be placed on the participant s face with tape. Their head will be positioned inside the MEG device. For the OP |
