Hi Thomas and all,

The kind of knowledges you ask for will not come from the blue.
It will need a brain scanner to see at molecular level how a brain
works, not a single neuron, not even a bunch of neurons on a flat
surface without glial cells nearby. The QND scanner will not be
 built from scratches, at least 3 steps will be requirred, the
build back software will be too a multistage process. Each step
will uses information recovered by the current cell/ brain analyser
at hand.

I think before the full brain reader is built, with 2000 elementary
beams, each with 1000 different frequencies, a last step demonstrator
with one beam and one frequency will be built.

Before that, an X-ray interferometer with holographic capability (to
see at a precise position in the 3rd dimension) must test the non-
QND componments.

Even these major steps must be further split out in more smaller
scale projects. Each is not only a technological step to go to
 the next system, it is also an investigation instrument of its own
and must bring some new knowledges about the brain in particular
and cells in general.
