All of the above, the wonder is that Jerry was suspended at all!  This
is the first time a clear coroner's case was diverted into a cryonics
organization without being hacked up in an autopsy.  Saul Kent and I
commented independently that this seems to be a side effect of all the
very expensive litigation Alcor has been involved with in the last few
years.

I can give you a more definate answer when we bring the lot of them
out of suspension, :)  but from what we see in animal brains, there is 
surprisingly little disruption of the critical structures up to perhaps
12 hours.  The biggest problem with longer ischemic times is that it
becomes very difficult to get much cryoprotective (glycerol) into the
brain before it swells and closes the blood vessels.  Keith Henson
