Unconditioned taste preference. Intakes for four taste solutions were compared against intakes for water (n = 5–6/group) during 48 h two-bottle tests. Spinophilin knockout mice (white bars) and wild-type mice (black bars) intakes were not significantly different from one another for any two-bottle test. Both genotypes showed a strong preference for 5% sucrose (A), preferred water slightly >75 mM NaCl (B), and avoided both 30 μM quinine sulfate (C) and 0.01 M HCl (D). (††) P < 0.01 vs. water.
