Data Acquisition at NatMEG
At NatMEG, MEG and combined MEG/EEG recordings are typically run by two people working in parallel: one focusing on the participant and experiment, and one focusing on the recording system.
Person A: Responsible for participant preparation, interaction and running experiment. Person B: Technical preparation and MEG recording monitoring.
General workflow:
| When | Person A | Person B |
|---|---|---|
| Before ppt arrival | Check experiment and equipment | Turn on OPM system |
| PPT in prep area | Prepare ppt | Record empty room |
| PPT in MSR | Adjust sensors | Adjust sensors |
| Before recording | Test experiment | Initiate and localize sensors |
| During recording | Run experiment, communicate | Record and monitor |
| After recording | Bring PPT out | Record empty room |
| After recording | Clean up | Run SESHAT |
