MEG resources

Scanner

  • CTF 275 Channel MEG with 64 Channel EEG
    • MEG: 273 active axial gradiometers plus 28 active reference sensors used for synthetic 3rd gradient noise cancellation
    • EEG: 56 unipolar and 8 bipolar channels
    • 56 channel EZ cap or 21 channel individual EEG electrodes
    • MEG and EEG can be collected simultaneously using the same electronics and software
    • Vacuumschmelze AK3B magnetically shielded room (2 layers of mu metal and 1 layer of aluminum)
