Apparently transplanted neurons often do not need to be very
functional, as long as they produce neural growth factors making other
neurons sprout. This is likely a major influence on why embryonal
neuron transplants work as they do.
As for retaining their previous state, that is the big question right
now. My bet is that they do, but we do not yet have the
information. Let's hope the Prometheus Project gets there with the
frozen hippocampus slices.
