<p>The illustration on the left represents the mouse brain. The top dashed line represents the first coronal cut, 5 mm away from the edge of olfactory bulb. The bottom dashed line represents the second coronal cut, 2.5 mm away from the first cut. The illustration on the right represents the brain section isolated on the left. The tissue within the dashed rectangle, containing mainly corpus callosum and part of the cortex, was used for RNA extraction. Abbreviations: CC – corpus callosum; LV – lateral ventricle; aca – anterior commissure.
