I understand neurostatic means the opposite of neuroplasticity.

Google is indeed unhelpful; I had never Googled "neurostatic", and it's possible I have the term wrong. That said, I seem to recall reading it somewhere.

Interestingly, the lead-in for Neuroplasticity on Wikipedia[1] states:

> [Neuroplastic] contrasts with the previous scientific consensus that the brain develops during a critical period in early childhood, then remains relatively unchangeable (or "static") afterward.

So I feel cautiously confident that I did read it, quite possibly in old medical textbooks that are not online.

I used "precepts" just because it felt like it conveyed the right concept in context.

I hope that helps.
