Aging-related changes in working memory tested in the DNMP task. Each point represents the average percentage of correct arm choices per group. Only sessions with regular, short-delay trials and without SCOP treatment are shown. The dashed linefor the OVX2 group (open triangles) indicates the age-related decline before the estrogen treatment. Thecaret indicates the onset of the age-related decline in the appropriate group as a result of a post hoc test (p < 0.05). The asteriskindicates a significant difference from the OVX1 group (open circles) during the period (simple main-effect ANOVA; p < 0.05). Open squares, Sham.
