As you remember, at the beginning of this segment I’ve stated that our antenna began to develop before our actual birth. The first brain level that can be detected even before our physical birth is the delta level. Our brains are at this level while we are in our mother’s womb. So, as babies, we have stayed mostly in the delta level, until 2-4 years old.
