Fig. 7From: Retinal thinning of inner sub-layers is associated with cortical atrophy in a mouse model of Alzheimer’s disease: a longitudinal multimodal in vivo studyGray matter volume analysis in the visual cortex. a Region of interest used in the assessment of the visual cortex volume overlaid on a mean T2-weighted image. b GM volume in the visual cortex of WT (white circles) and 3×Tg-AD (black circles) mice measured by VBM analysis. Results are presented as mean ± SEM. The significance of the alterations in GM volumes of the visual cortex along time and between groups was assessed by an ANOVA repeated measures (mixed-effects) followed by a Bonferroni post hoc test. **p < 0.01 and ***p < 0.001. nWT = 6, n3×Tg-AD = 7Back to article page
