METHODS: The extracts of forebrain, midbrain,afterbrain and cerebellum of neonatal mice were prepared, and the NSCs of newborn mice were cultured in vitro. Neurospheres were observed, immunocytochemical staining of characteristic protein, nestin, and MTT assay were performed to identify NSCs and their proliferative properties.

In the brain of adult rat, the positive immunohistochemical product of lSL-l (ISL-l-positive) was mainly located in the neuronal nucleus and found in discrete regions except to brain cortex, such as the Purkinje cell layer and the granular cell layer of cerebellum, the granular cell layer and the pyramidal cell layer of hippocampus, the mitral cell layer, the internal and external plexiform layer, the granular cell layer and the granular cell layer of olfactory bulb and so on, and several nuclei of the hypothalamus, midbrain and pons, such as claustrum, anterior olfactory nucleus, accumbens nucleus, caudate-ptamen, pallidum, substantia nigra, striatum, islands of Callaje, mammillary nucleus, anterior pretactal nucleus, habenular nucleus, amygdaloid nucleus, cuneate nucleus, rubral nucleus, gigantocellular reticular nucleus and so on.

The activation of NRM neurons by electroaeupuncture was eliminated after decerebration at superior colliculus level, indicating that this effect of EA depends mainly on the supra-midbrain structure. Furthermore, all treatments including AR isolation, disconnection of #beta#-endorphinergic tract and micrpinjection of naloxone or anti-#beta#-endorphin serum into PAG, would make the effect of EA disappear. Thus, it is the #beta#-endorphinergic pathway between AR and PAG-NRM system that mediates the major excitatory effect of EA on NRM.

The activity of Cre recombinase is predominantly detected in the midbrain, diencephalon and olfactory bulb in the SCC4.4-iCre transgenic brain. However, it only can be observed in the caudal part of the midbrain in the SCC2.7-iCre brains.
