High-powered demonstration of rat brain by ex vivo micro-CT scan. Direct comparison between the sagittal section of rat brain in (a), micro-CT slice, and (b), H&E stained 4× light micrograph. Similar structural details are seen in these two imaging. (c and d) are respective 20× and 40× light micrographs of selected FrCtX region, demonstrating neuronal cell bodies. Anatomical structures of comparable visibility are labelled as follows: Acb = accumbens nucleus; AO = anterior olfactory bulb; apons = anterior pons; ATh = anterior thalamus; CA1 = CA1 field of hippocampus; CA3 = CA3 field of hippocampus; CER = cerebellum; CPu = caudate putamen; EPi = external plexiform layer; FrCtx = frontal cortex; Hypo = hypothalamus; IC = inferior colliculus; Med = medulla; OV = olfactory ventricle; Pit = pituitary gland; PTh = posterior thalamus; SC = superior colliculus; Th = thalamus
