But something like influence from the prenatal environment is environmental—in the sense that it's not genetic—but it can't be changed after birth. We should be careful about thinking genetic/non-genetic equates to "stuff we don't control/stuff we control".jaedhttps://www.blogger.com/profile/03328666344764784829noreply@blogger.comtag:blogger.com,1999:blog-19305198.post-53762940234210080532018-01-14T07:59:26.573-05:002018-01-14T07:59:26.573-05:00@ Tom - that is an excellent example of exactly wh...@ Tom - that is an excellent example of exactly what I meant.

In my work we see a lot of brain MRI and CT scans. The radiologists often note physical differences in circulation that are far from the textbook norm. Arteries running where arteries don't normally run, or lacking, or one branch being much smaller or larger than the norm. All, apparently, normal variation of unknown origin. When the basic body plan is laid down in the fetus, a lot of chance is involved.<br /><br />The second thing is that reductions in blood flow reduce alertness. The docs will go in and ream out or balloon a blocked artery, and if all goes right the patient regains a lot of mental acuity. A pre and post IQ test would I expect show a big jump after a successful proceedure.<br /><br />My point being that whether you are born with good blood flow or not is largely chance. It isn't environment or genetics. It's just chaos in those first few weeks after conception when the basic body tracts are laid down.
