Table 1 Test compounds and test series for 30 B6 and 30 D2 mice. Each mouse was tested with three compounds (2 consecutive test sessions per compound) over a two-week period. Stimuli were KCl, cycloheximide (CYX), raffinose undecaacetate (RUA), 6-n-propylthiouracil, quinine hydrochloride (QHCl), denatonium benzoate (DB), and HCl. A total of 10 mice were tested from each strain (5 males, 5 females) for KCl, CYX, PROP, MgCl2and QHCl. A total of 10 mice from each strain (5 males, 5 females for B6; 7 females, 3 males for D2) were tested with DB and HCl. A total of 11 B6 mice (6 females, 5 males) and 9 D2 mice (5 females, 4 males) were tested with RUA.
