PSD-95 KO show impaired lithium chloride conditioned taste aversion. (a) WT and KO showed high, similar malaise scores following LiCl injection. (b) KO had a significantly lower aversion index than WT during probe tests 1 and 14 days after conditioning. The aversion index was significantly above chance in WT, not KO, on both test days (n = 8–10/genotype). Data are Means ± SEM. #P < 0.05 versus 50% chance/same genotype, **P < 0.01 versus WT/same test day
