O...K... wait a minute, did Whisper just make a dump of that girls brain just as she died?"Copied a good portion of her neural block unto a quarantained partition"
The brains neural architecture is at least somewhat redundant. Some bits missing will cause sporadic but not necessarily irreversible amnesia.
But to decode those memories, you have to run the neural network in simulation. Aka upload her into a very capable neural processor of some sort, run some neural architecture equivalent of fsck. Put all I/O through a really good firewall, and then start her up.
"Hi. Welcome back. I have some bad news for you, you just died, and I transferred you to a virtual system. But that doesn't matter, you still know something you want to tell me, and now I can turn on or off as much virtual pain as you like. Much better, isn't it?"
