Subject: Uploading
From: Keith Henson <>

To completely muddle the concept of uploading, consider your brain
being infiltrated by nano devices on the same scale as the number of
cells in the brain.  The devices are small enough so there is plenty
of room for them without expanding your skull.  The devices can both
read and stimulate nerve cell activity.  There are no physical
barriers I can think of that prohibit building such nano machines.

In monitoring mode, the devices map out all the signal pathways and
learn to predict what inputs result in specific outputs.  They build a
parallel brain and operate it long enough to be confident the brain in
the nano devices duplicates the running brain, including the formation
of long and short term memory.

Now we cool the brain or otherwise shut down the firing of the nerve
cells, but let the parallel brain continue to operate.  Activity
continues in the parallel brain which now takes over forming long and
short term memory.  After hours to days, we warm up the natural brain
and synch it to the nano devices.

There is no reason I can think of that subjective consciousness would
not persist across the cool down and warming up of the natural brain.

I used this in "The Clinic Seed" to painlessly seduce people out of
the physical world.
