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.
