Abstract:
Intranasal injections of a fragrant solution of 2-methyl-2-thiazoline elicited significant heart rate decelerations in late pregnancy fetal sheep, while the injection of a control fluid (isotonic saline) had no effect. This result indicates that the ovine fetuses are able to detect nasally administered odorants, as previously demonstrated in the fetuses of murine rodents.
