In msg #1474 Steve Harris gives us good reasons to believe (in the 
case of a well attended cryonicist dying under expected conditions) 
that relatively minor neurological damage occurs before clinical death.  
His arguments are certainly well supported by the literature about 
shock; while other parts of the body (kidneys and liver) might suffer 
considerable damage from prolonged low blood flow, the brain seems to 
be rather well protected from similar damage--at least down to the 
point where breathing stops.  As a practical matter, I will quit 
worrying about pre clinical death brain damage. 

Unfortunately, only two of the last six patients had prompt and 
very effective restoration of well oxygenated blood flow to the brain 
following clinical death, so *post* clinical death neurological damage 
is still a serious concern.  I can go into the details of these cases, 
and look up more cases, if anyone is interested.
