Hup A did not affect learning in mice. (a) Exploration times for the two identical bottles in each group (two-way RM ANOVA, objects: , ; groups: , , for control and clonidine group, for Hup A group). (b) The control and Hup A groups spent more time exploring the novel object (two-way RM ANOVA, objects: , ; groups: , , for control and clonidine group, for Hup A group, under SNK test). (c) The discrimination index did not differ between the control and Hup A groups (one-way ANOVA, , ; under SNK test). DI indicates discrimination index.
