Median Preoptic Nucleus Mediates the Cardiovascular Recovery Induced by Hypertonic Saline in Hemorrhagic Shock

Figure 1

Typical injection site in the median preoptic nucleus (MnPO). (a) Photomicrograph of a coronal section of the forebrain of a representative site following a nanoinjection labeled with 4% Evans blue dye (arrow). (b) Four sequential coronal drawings showing the maximum (dark area) and minimum (gray area) extent of dye diffusion into the MnPO. Red spots indicated the extent of dye diffusion outside of the MnPO.
