A The experimental timeline of the behavioral procedure and ANA-12 local injection. B Schematic showing the local infusion of ANA-12 in DG in adult C57BL/6N mice. C Compared with control mice that successfully distinguished the displaced object from the stationary one, ANA-12-treated mice showed impaired spatial recognition memory. D In the Y-maze spontaneous alternation task, ANA-12 infusion did not significantly affect spatial working memory. E The experimental timeline of the behavioral procedure and 7,8-DHF microinjection after ELS exposure. F Schematic showing the 7,8-DHF infusion into the DG in adult C57BL/6N mice. G In the SOR test, except that the ELS + Veh group failed to recognize the object placed in novel location, the other three groups performed well. H In the Y-maze test, microinjection of 7,8-DHF in DG did not significantly affect spatial working memory.
