The point at which true irreversible death occurs is brain death. http://en.wikipedia.org/wiki/Brain_death

A heart is stopped, you can make it go again in some circumstances. A brain ceases activity and you cannot make it go again. 

"Has anyone else heard that apparently after you die your brain activity continues for a few minutes?" No. But I can understand that the sentences original intention was probably thus:

"Has anyone else heard that apparently after  you die your heart stops beating your brain activity continues for a few minutes?"

I hope that this helps.

You're welcome. 

OK I had a little dig for you and found this:

"Without special treatment after circulation is restarted, full recovery of the brain after more than 3 minutes of clinical death at normal body temperature is rare"

http://en.wikipedia.org/wiki/Clinical_death and I read the abstracts of Wikipedia's references - seems legit.
