In WT animals, responses to all tastants except 5 mm quinine were larger under urethane
anesthesia than with
pentobarbital (Fig. 7B, Table 4), but this difference in response magnitude with anesthetic did not occur in the KO mice (Fig. 7C, Table 4), with the exception of sucrose.
General
anesthesia was induced by intraperitoneal injection of
pentobarbital sodium (Sanofi, Libourne, France) just before killing by exsanguination.
