I read in some article some time about use of SQUIDs (https://en.wikipedia.org/wiki/SQUID) to map activity of a single neuron non-invasively. There was a lot of hype at the time for brain-computer interfaces based on that, but then same as with many technologies that were "just 5 years away" those 5 years came and went with no deliverables expected.
