[demosthenes the elder]

very well, I see that I shall have to venture into a spider infested attic, locate a dusty old box, and dig out a book I have not seen in a decade, and see what is has to say.
I shall not, however, do this at 330am.
In the meantime, a question for you: If, as you assert, the brain is fully formed before birth, why does the volume of the cranial vault expand dramatically over the span of the next five-plus years? In fact, if the brain is fully formed, why are children born with fused cranial sutures in inevitable risk (barring extreme corrective surgery) of brain death due to a lack of such cranial vault expansion?
Just something to chew on in the nonce.

If, as you assert, the brain is fully formed before birth, why does the volume of the cranial vault expand dramatically over the span of the next five-plus years?

All the neurons are present, but glial cells (helper cells), and synpases (connections) continue to grow. But of course this occurs well past birth throughout your life, and yet no one would seriously consider murdering a healthy newborn child.
