1. How many chanels can ensure magnetoencephalograma from the scalp ? The
best EEG resulution can be about 1 cm. What is SQUID resolution ? (I read
about SQUID system with 256 chanels. Is the more chanels is possible ?
How many ? Also I read, that digital SQUID system can ensure 100 Msamples
per second speed. But the other limit is resolution, I think).
2. How about MEG from the implanted electrodes ? Is the any real system
3. How about SQUID in the liquid nitrogen temperature ?
4. Do you know any commercial (not experimental) SQUID system for brain
