Information content with low- vs. high-T c SQUID arrays in MEG recordings: The case for high-T c SQUID-based MEG.

Highlights: [•] We model low- and high-T c SQUID arrays in MEG recordings of neural activity in the brain. [•] We compare the total information available to these SQUID arrays. [•] An MEG system based on high-T c technology is capable of producing at least 40% more information than the state-of-the-art in low-T c MEG systems. [•] The gain in information provided by high-T c MEG technology is a result of the closer source-to-sensor standoff distance. [ABSTRACT FROM AUTHOR]
