Not sure is this would be better than brainbow in zebrafish, need to read more thoroughly.
On vasculature possibly guiding nerve growth:
Being clueless can be advantageous:
How does this apply to scientific exploration?
Here is a dilemma: if you have $5,000, should you buy a used car or sequence your genome?
If you just wait, both will get cheaper :-
