[extropy-chat] The Story of a Brain

[Adrian Tymes]

As others have noted, the "impulse cartridges", if
they work as described, essentially completely
replicate the individual.  But there is also a second
discontinuity point: when the later individual
substitutes his own brain for the (now dead) original
neuron.  One could easily argue that - even if it is
just a small amount - this is substituting part of the
later individual for the earlier one, and thus no
longer a true recreation of the earlier individual.
A very, very close approximation, perhaps not with
immediately measurable differences, but different (and
likely eventually measurably so) nonetheless.
