We recently reported greater sensitivity in PND11 pup compared
to PND17 (Moser et al., 2010). Given an unexpected availability of
younger rats, it was of interest to include a comparative study using
PND11 pups; however, we were only able to test dicrotophos (0, 0.11,
0.21, 0.53, 1.06 mg/kg, n=7/dose).
