查询词典 midbrain

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. The results suggest that CYP11A1 gene expression could be differentially regulated in different regions of the brain.

结果发现，4.4 kb与2.7 kb之CYP11A1启动子皆可使Cre重组酶表现於胚胎脑部，前者主要表现在中脑、间脑及嗅球，后者仅主要表现在中脑尾端，说明了CYP11A1在不同脑区表现所需的元素有所不同，可能有不同的调控机制。

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.

Encephalocoele is a common congenital malformation whose mechanism was no known. NO participates in the physiologic process of brain.

胚胎脑发育的早期阶段主要是神经板隆起、弯曲、闭合形成神经管，神经管的头部从前向后依次发育形成脑的基本组织形态，即端脑、间脑、中脑、后脑，在神经管闭合过程中出现异常就会导致NTD。

Birth defect in which the forebrain and/or midbrain are diminished in size or are missing.

无脑出生缺陷里前脑和中脑在大小上是减少了或者是遗失掉了。

B. The human nervous system is organized along horizontal and vertical axes because of the cephalic flexure at the junction of the cerebral hemisphere and midbrain.

而人类神经系统的发展则是沿著水平和垂直发展。

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.

在正常成年大鼠脑中，同源框基因islet-1表达产物（ISL-1）免疫组织化学阳性物质广泛分布于除大脑皮层外的神经细胞的细胞核内，ISL-1阳性神经元密集分布于小脑Purkinje细胞层和颗粒细胞层、海马的颗粒细胞层和锥体细胞层、嗅球的内丛层、外丛层、颗粒细胞层及僧帽细胞层等，另外在丘脑、中脑和桥脑的一些重要神经元核团均有分布，如，屏状核、前嗅核、伏核、尾壳核、苍白球、黑质、纹状体、Calleja岛、乳头体核、前顶盖前核、缰核、杏仁核、楔束核、红核网状巨细胞核等。

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.

检验AR至 PAG-NRM的神经通路在电针效应中的作用：实验显示上丘水平去大脑后，电针兴奋NRM的效应完全消失，表明此效应主要依赖中脑以上结构实现，进一步分别用Halfisz氏刀游离AR、切断AR至PAG的β-End能束、PAG内注射纳洛酮或抗β-End血清后，也使电针效应基本上完全消失，说明电针使NRM神经元兴奋的效应，主要通过AR与PAG-NRM间的β-End能神经通路实现。
