Editor’s take
In favor
- Movement-tolerant — subjects can move while being recorded
- Helmet sizes for infants and children, not just adults
- Room-temperature sensors — no liquid helium required
- Exports to standard MEG analysis stacks (MNE, FieldTrip, Brainstorm)
Against
- Requires a dedicated magnetically shielded room with active field-nulling coils — large capital cost
- Cannot be operated outside a shielded environment
- Lower sensor count than mature 300+ channel SQUID-MEG (sensor count grows with each install)
- Sensor supply chain depends on QuSpin QZFM availability
