Look, even arguendo, before you can get into pre and post discussion, one must first clearly delineate what stage of embryonic development you are talking about. For example, a zygote has less in common with a full term embryo than say a full term embryo has to a 1-minute-old born embryo, i.e. baby. But that does not automatically mean that all embryos are ipso facto babies.
But more to your point
> any facts people could give me about maybe synaptic pruning or whatnot that might set a stage to have **this discussion**
What discussion are you trying to have exactly?
