MEG Data Acquisition Checklist
Click on the checklists to mark your progress through data collection.
Prepare Control Room & MSR
-
Check functioning of stimulus and response equipment.
- Select the correct Stim PC via KVM.
- Press button 1 to connect to the OLD Stim PC.
- Press button 3 to connect to the NEW Stim PC.
- LED Meanings
- Green/Dark for connected PCs, but not active.
- Green/Red for connected PCs actively using the KVM.
- Dark/Dark for no connection.
- Select the correct Parallel Port via the Parallel Port (PP) Switch Box.
- Use PP Switch position A to connect STI101 to the OLD Stim PC (PP Base Memory Address: BFF8)
- Use PP Switch position B to connect STI101 to the NEW Stim PC (PP Base Memory Address: CFF8)
- Select the correct Stim PC via KVM.
-
Check Gantry position. Move from Liquefaction (25) position to usage position - [Moving the Gantry]
-
Check experimental paradigm.
- Check the PROPixx projector is "awake" (make sure lens cover is removed).
- Start the VPutil program, from the Stim Desktop shortcut, and type...
- (ANY DEVICE) >
ppx a
- should respond with "PROPixx is in awake mode" - To "sleep" the projector ...
- (ANY DEVICE) >
ppx s
- should respond with "PROPixx is in sleep mode" - Please do not leave the PROPixx projector in "awake" mode when not in use e.g. overnight!
- NOTE:
ppx a / ppx s
didn't work on one occasion. PROPixx needed a full power off/on to reset.
- NOTE:
- Check that the stimuli and responses are as expected.
- Check arrival of triggers in MEG recording.
- NOTE: New Stim PC PP card has a different Base Memory Address than the OLD Stim PC.
- Change any, e.g. MATLAB, code on the NEW Stim PC, referencing the PP Base Memory Address to...
- CFF8 ... e.g. in
initialiseParallelPort.m
- CFF8 ... e.g. in
- Change any, e.g. MATLAB, code on the NEW Stim PC, referencing the PP Base Memory Address to...
- NOTE: New Stim PC PP card has a different Base Memory Address than the OLD Stim PC.
- Check the PROPixx projector is "awake" (make sure lens cover is removed).
-
Start subject preparation, items to have ready/available.
- Label electrodes for EOG (2), ECG (2) and any other (i.e. EMG) electrodes. Have some additional ready in case you have to redo them.
- NOTE: Reusable and disposable electrodes are available.
- Electrode gel (in 20ml syringes - use the caulking gun to fill them.) We also have 12ml curved tip syringes now available.
- Cut tape ready for attaching electrodes to skin (Tegaderm tape)
- Tape for securing electrodes (Micropore tape) and small double-sided discs.
- If using an EEG cap, check it over for damaged electrodes. Makes sure it's clean and dry.
- Set up the Digitizer chair, away from any metal. Attach the receiver cube to the back of the chair. The cable has to point downwards.
- The locations of our various consumable items can be found here
-
Check the MSR for any unwanted items that could cause artefacts and remove them.
-
Check that the participant monitoring camera and microphone are working correctly.
Prepare MEG system
- Prepare system.
- Check quality of channels.
- Click "Noisy Channels" for more information
- Select or create project.
- Check or select acquisition parameters.
- Check or create online averaging parameters'
- Create subject.
Prepare subject
- Offer bathroom break.
- Explain preparation procedure.
- Explain experiment.
- Let subject read and sign informed consent.
- Have subject remove metal objects, and do a comprehensive check with both metal detectors. Subject to change into scrubs if necessary (show subject to Changing Room and show scrubs sizes that are available).
- We are trying to reduce our laundry bill so only use scrubs if necessary e.g. metal in clothing.
- Clean hands with Alcohol Gel Sanitizer.
