All MEG studies require the presence of a qualified "MEG Operator", as defined in the [attachment:CBU_MEG_SOP_11_020507.pdf the Standard Operating Procedures (SOPS)] which you need to read before running any studies in the MEG lab. The Operator will actually run the MEG machine. | '''[[ConvertingE-PrimeScripts]]''' |
Line 4: | Line 6: |
Please, note, that to run your study with an operator, you will have to become authorised as an MEG researcher. The authorisation procedure is described in the SOPs; briefly, it includes a general introduction to the lab by a qualified operator, reading the SOPs, an assessment of your knowledge of the procedures (particular attention is paid to volunteer and equipment safety aspects) and attending an ongoing MEG study. | '''InterCom''' |
Line 6: | Line 8: |
Even though it is the Operator who will run the data acquisition machine, proper project settings for data acqusition are a responsibility of a particular MEG researcher. Please, once you are ready to run your study, contact the operators well in advance to discuss the settings and stimulation requirements. | '''[[Resources]]''' |
Line 8: | Line 10: |
Running the stimulation computers and making sure your paradigm is compatible with the MEG machine is the researcher's responsibility. The operators will not run your stimulus delivery programs for you. | '''[[StimulusDetails|Stimulus Presentation]]''' '''[[ResponseCollection|Response Collection]]''' '''[[Triggers]]''' '''[[EyeTracking|Eye Tracking]]''' '''[[SubjectPreparation|Subject Preparation]]''' '''[[CheckStimulusBeforeTesting|Check Stimulus Before Testing]]''' '''[[AcquisitionTips|Acquisition Tips]]''' == General == === Before you start your study === * You have to become a "Qualitified MEG Researcher", as outlined in our [[http://intranet.mrc-cbu.cam.ac.uk/imaging/meg/megdocuments/|StandardOperatingProcedures]] (SOPS).

Running MEG studies
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 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.
