I don't recall saying anything of the sort

Well, I'm not sure what else to make of the "hard limits" regarding the magnetic field that a human brain can "take" that you were referring to. What exactly did you mean?

There's still an occupational safety risk around strong, static magnetic fields.

Such as? What occupational risks are so elevated at high field that they would pose a "problem" to human brain imaging?

but then this analogy makes it seem possible

Maybe it is, maybe it isn't. I wouldn't hold my breath if I were ... (read more)

As passive_fist already covered, the strength of the magnetic field is mostly irrelevant in terms of safety. The human brain doesn't suddenly stop functioning at 11 Tesla, nor does it get heated by the static magnetic field. Radiofrequency heating safety at high field is still an ongoing topic of discussion, but it should (presumably) not be insurmountable problem, and there are technologies in development that may reduce the required RF power substantially.

The bigger question, assuming you were being serious with your reference to uploading, is what MRI c... (read more)
