Percent of time spent in each chamber of the apparatus during the 15 minute pre- and post-conditioning tests. Values are plotted as percent of the total 900 second testing session spent in each compartment, independent of the compartment in which they received conditioning injections. All values are means + S.E.M.; n values are illustrated in the compartment in which the mice were conditioned (i.e., for COC40, saline, n=9 mice). * =P<0.05 vs. pre-conditioning. See Results for details.
