Newborns eyes flutter and arms shoot out

Our baby boy is 10 weeks old. This has happened about 6 times. We have noticed everytime it has happened my wife was taking the baby down from her shoulder and laying him down on the changing table. Our pediatrician did not seem to concerned, but did refer us to a nueroligist as a precaution. We have the apt next week. It just happened again as my sons head snapped back as he slipped off from breast feeding. I saw the "episode" for the first time and it is very disturbing. I saw someone post something here a while back on the same topic. It looks more serious that a Moro, or startle, reflex. His eyes sort of "freeze" and flutter side to side. He is unresponsive for about 10 seconds, then back to normal. Thanks in advance for your help.
