I blogged about Plastination, a potential alternative to cryonics, and suggested storing, along with the patient, an EEG of their healthy brain activity.
Some people misunderstood the point of doing that. It is to provide a potential cross-check. I won't try to guess how future simulators might best use the cross-check.
And it isn't intended to rule out storing fMRI or MEG data also, although neither seems practical to get every six months or so.
But what to my wondering eyes should appear a few days after I wrote that? MEG-MRI, a technology that claims unprecedented accuracy in measuring brain activity.
So I wrote this follow-up post to note that MEG-MRI as another potential source of cross-checking information.
