An example of automatic detection of neurons and their processes from
BrainMaps data.  This is from layer 6 of the cortex of a monkey.
Green indicates the detected cell bodies.

I think the first structural upload of an entire brain may not be far
away.  There are significant computational resources required (there's
a lot of data and multiple slices need to be carefully registered
since they distort non-uniformly) but I think the necessary compute
power and storage will be available cheaply before this decade is out.

Reverse engineering the detailed structure of the brain won't give us
a "mind upload", but it will be a useful first step in that direction,
greatly assisting with the development of plausible theories about how
the brain really operates.
