Yes, they seem to have the same

concern that they were blocking only the VNO, and not olfactory surface as well.

But this is still a

fundamentally better test than what the Erox folk were doing... they were administering the pherins directly to the

VNO through some device, and measuring electrical potential changes on the VNO. I'm not saying they didn't pull

that off, but that's a pretty difficult medical and engineering task. Blocking off the VNO sounds a whole lot

simpler. And now that -dienone effects are well established this seems to be a clever experiment to test for

possible VNO activity.
