Fig. 3. Thalamus and other regions were also severely damaged after neonatal exposure to sevoflurane (Sevo). Sagittal (  A and  B ) and coronal (  C ) views of the mouse brain after exposure to room air for 6 h (  A ) and to 3% sevoflurane for 6 h (  B and  C ) as described in  figure 2. A substantially higher density of cleaved caspase-3–positive profile is present in thalamus (th) as well as subiculum (s), inferior colliculus (ic), and pontine nuclei (pn). rs = retrosplenial cortex.  Scale bars : 1 mm.
