This picture shows the ActiveOne used in a simultaneous EEG/MEG evaluation at The KNAW MEG center, Academic Hospital of the Free University, Amsterdam, The Netherlands
  Extensive tests conducted at this site proved that the very low-noise low-power digital circuitry of the ActiveOne system did not in any way interfere with the sensitive magnetic bio-current measurements.
 

In this application, the ActiveOne is used with our optional bufferboxes and passive nonmagnetic electrodes (Active electrodes would not have any advantage in the shielded room, in fact they might be a disadvantage because the currents in the active electrodes might in interference with the small bio-current being measured)

 
 
up to 256 biopotential channels
Synchronization with sample rate of MEG is possible
DC-measurements
Easy installation, no power connections, just 1 fiber goes through the wall of the shielded room.
System is easily removed for all your applications outside the MEG.
