Brain plasticity is quite remarkable, but imperfect. The fact that advanced alzhiemers patients can even talk at all is a testiment to that fact. (Their brains look like pustulent swiss cheese)
The problem is that adult stemcells do not turn into new nervous tissue, with the exception being in the olfactory bulb. What grows are axons and dentritic connections.
Plasticity is the migration, pruning, and creation of those connections.
Mylenation is a very biologically expensive process, (gial helper cells spend most of their active lives slowly depositing the mylein sheath around their client axons) so the brain establishes primary axon routes prior to mylenation. Once mylenated, the axon is essentially dedicated hardware, and only the dentrite connections change.
Luc Bakecakes is a girl. She learned the secrets of life and death shortly before she married and shortly after becoming obsessed with her own mortality, and taught them to several necromancers over the years. She still lives happily in Loverauthors. I plan to adventure there when I get the chance.
Ive very much enjoyed the neuroscience so far, especially this most recent argument that the only way you could be immortal and not watch your skills slowly deteriorate is to be high on weed the whole time.
But you know who else is immortal and spends all their time growing weeds... ELVES! Magma him!!!
So, she is basically the evil version of strawberry shortcake?
Perhaps a "kindly old grandmotherly" type who bakes cookies and cakes while raising the dead? For some reason I have no difficulty at all seeing this....
