a–d GFAP-labelled astrocyte cell counts (±SEM) normalized to non-surgery counts in the hippocampus regions CA1 (a), CA2 (b), CA3 (c), and dentate gyrus (DG) (d). e Representative images of the CA1 region of wild type mice fed safflower oil (WTSO), fat-1 transgenic mice fed safflower (fat-1), and wild type mice fed fish oil (WTFO) prior to surgery (baseline, top two rows) and at 10 days post-intracerebroventricular infusion of amyloid-β peptide (bottom two rows). The top rows for each time point are images enhanced for contrast and sharpness for publication; bottom images are the same images in which a threshold was applied to show labelled cells. Two-way ANOVA applied, where significant main effects are reported beneath each graph. CA cornu ammonis, DG dentate gyrus, GFAP glial fibrillary acidic protein. SEM standard error of the mean
