rtMEG: A Real-Time Software Interface for Magnetoencephalography

Gustavo Sudre, Lauri Parkkonen, Elizabeth Bock, Sylvain Baillet, Wei Wang, Douglas J. Weber
2011 Computational Intelligence and Neuroscience  
We have developed a software interface to stream MEG signals in real time from the 306-channel Elekta Neuromag MEG system to an external workstation.  ...  The signals can be accessed with a minimal delay (≤45 ms) when data are sampled at 1000 Hz, which is sufficient for most real-time studies.  ...  Acknowledgments The authors thank the University of Pittsburgh Medical Center (UPMC), Center for Advanced Brain Magnetic Source Imaging (CABMSI) for providing the scanning time for MEG data collection.  ...
