My problem here is: If a brain may be scanned so that its content can be 
built back and run in an electronics system, can we next do the inverse 
operation, namely downloading the electronics information in a biological 
brain?

A very advanced solution would to use 3D modeler to make an atom sharp 
picture of the original brain, load that in an analog quantum computer and 
then use a form of quantum entanglement to copy that structure in a "blank" 
brain: The ultimate brain washing technology :-)

We may think of that as a potential technology, but assume we have some money 
to spent on the problem today, where do we start? There is no clear program 
able to connect the present day state of affairs with that dream tech. My 
personnal feeling is that simple entanglement is too frail to be extended to 
the mass and volume of a full brain at room temperature. So, sorry to come 
back with that subject, but nonlocal fields and non continuous ones seem a 
requirement before anything more can be done in that domain.

I turn now to a more simpler solution. I have said how a micrometer scale 
printed circuit could be built from clay crystals. The idea is to use that 
technology to build a two ways radio link. On face 1 of the flat crystal 
there would be both, a fractal antenna for microwaves and a capacitor to 
gauge the nearby electrical field. On face 2, a rectifier would produce an 
electric current from the wave received in the antenna. That electric current 
would power a digital receptor and an emitter. A chemical marker would be 
fixed on the crystal so it would get fixed on a neuron receptor of a given 
kind.

A number of devices, with tags for different neuro-receptors would be 
injected in the brain. They would be attracted and get fixed on their neuron 
target. Powered from outside by a radio wave, they would broadcast the 
electrochemical activity they sense in their environment in messages 
including an individual code. Outside, an interferometric receptor would 
recive the message, localize the source and identify the code. So the 
information recovered would be in the form:

Crystal number X has seen the electrochemical activity Y at site Z.

An exterior broadcaster could then send the message V with code W so that 
only the internal receptor W use it.

This system would link many, may be most, neurons in a brain to an exterior, 
electronics system. The message Y at site Z in the brain would so go not only 
to the next neuron, but too at a group of artificial neurons in an 
electronics device. The output of these neurons would then be sent back in 
the brain.

One use would be to expand the brain power. Here, the artificial neurons 
would contain no information at start, they would be only brute force power, 
every information and trainning would come from biological neurons in the 
original brain.

Another possibility is that the electronics neurons have the content of a 
brain. The biological brain could be build from recently differenciated stem 
cells and have no information in it. The biological "zombi" brain would then 
be trainned by the electronics part.

The main advantage of that technology in the short term is that we know how 
to start with it: Buy a phase contrast microscope to select a kind of clay 
crystals. Move to electron scanning device to see the crystal surface at near 
atomic resolution. Use an atomic force microscope and "laser cooking" to 
shape the surface so electronics components can fall in their intended case.
