Update on the u/s journal article

Despite USA today saying that the article regarding the effects of prenatal u/s on brain architecture was published on Tuesday, it wasn't available to us peons until yesterday. Here's the link, if you're interested.

Reading through the original article I had found, they don't misrepresent anything, but I do feel much better after having read the source document.

For one thing, the mice were exposed to the u/s for a much longer percentage of developing brain time than any of our babies are. Plus, no effect was seen until 30+ minutes of exposure to a stationary u/s beam. Our u/s don't take nearly that long, nor is the beam stationary. Even if cumulative exposure is > 30 minutes, I think there's long enough between exposures that different cells would be "affected" with each scan, not enough to cause the kinds of changes seen in this study.

That said, I still think it's worth considering the value of each u/s before having it.

37 weeks tomorrow. Mind boggling, as many of you commented on my previous posts. And acupuncture / moxybustion scheduled for tomorrow as well to try and get Phred to "assume the position". I'm really hoping that it works!!!

I've got my fingers crossed it works. Turn Phred turn!

Wow...37 weeks! It doesn't seem that long ago that you just found out you were pregnant.

Hoping that Phred gets that head down for you. It won't be long now.

Take care
