General

Before you start your study

  • You have to become a "Qualitified MEG Researcher", as outlined in our StandardOperatingProcedures (SOPS). This can take up to about 4 weeks. Contact mri.admin@mrc-cbu.cam.ac.uk to start the process.

  • You need IMC/IIG approval for your study.

  • You have to create an acquisition set-up for your study, e.g. specifying whether you will record EEG, EOG, ECG, low-pass filters etc. You should contact Olaf Hauk well in advance in order to arrange a meeting in the MEG lab.
  • Every MEG recording needs to be operated by a "Qualified MEG Operator" (see SOPs). If you want to operate recordings yourself (in company of another qualified researcher), you need to undergo additional training as specified in the SOPs.

During Data Acquisition

  • While it is the responsibility of the qualified MEG operator to make sure the recording is running smoothly, the researcher should make sure all the settings for stimulus presentation and data acquisition are correct.

These are a few things to look out for at the beginning of each recording:

  • Check if stimulus presentation equipment and response collection work as desired (are stimuli audible, visible etc.?)
  • Has the correct preparation (incl. digitisation and subject ID) been loaded?
  • Have the correct project and acquisition settings been loaded?
  • Are triggers visible in STIM channel?
  • Does the EEG look ok? Note bad channels.
  • Are HEOG/VEOG/ECG in correct channels and look ok?

If you are using any non-standard equipment or make any changes in the settings (be they hardware or software), make sure to undo your changes in the end of your recording slot and leave the lab in the same state you found it before the recording.
