title: Fetal magnetoencephalography: current progress and trends.
abstract: Multimodal testing is the key to successful fetal neurological assessment. New mutichannel SQUID (Superconducting Quantum Interference Device) sensor devices can now be used to effectively record fetal auditory evoked responses (fAER) and visual evoked responses (VER), spontaneous brain activity, and heart activity. In this paper, we review the current progress in the area of fetal magnetoencephalography (fMEG) and also present an overview of the studies performed using a system called SARA that is specifically designed for fetal MEG studies. With the capability of recording spontaneous and evoked magnetic fields, we believe the monitoring of the neurological status of the fetus can be effectively implemented and can encourage the development of new strategies of intervention for the high-risk fetus.
