No pain at ANY POINT??? This "research" doesn't pass the smell test.
Indeed. In fact, I once asked whether Logan, FR's own adopted Texas Termite preemie felt any pain after his very premature birth. The answer was, of course, "yes."
And of course, if the baby cannot feel pain during gestation, obviously she cannot feel or hear or otherwise sense anything else, either -- pain is just one sort of nerve impulse, after all. But we know that the fetus responds to various stimuli while in the womb.
It's complete bullshit, in other words.
This is just a guy trying to justify abortion, and he's trying to find an argument that can't be fought with ultrasound pictures.
Wasn't there a video called Silent Scream that pretty well answered this question in the affirmative? One often wonders at the idiocy of some investigators.
