美国克利夫兰消息:凯斯西方保留地大学医学院的研究人员第一次纠正了小鼠大脑重大的先天缺陷,从而对人的(如脊柱裂)一些先天缺陷的解决带来了新的希望。发育遗传学和解剖学副教授Jerry Silver说:“小鼠胼胝体发育不全(胼胝体的形成不越过大脑中线的一种先天畸形)可以基本上治愈。”为了确定大脑在发育中是否存在为神经纤维提供非神经细胞通路,Silver对胼胝体进行了数年的研究。选择胼胝体进行研究有几种原因:第一,它体积大。在小鼠中,它由约300,000根纤维组成,而在人体中,由约3亿根纤维组成,由于它位于大脑表面附近的大血管下面很易接近。这意味着我们在不损伤过多的脑组织情况下能够达到它。第二,有一种胼
Cleveland, United States: Researchers at Case Western Reserve University School of Medicine, for the first time, corrected major brain defects in mice and brought new hope for the resolution of some of the birth defects of people, such as spina bifida. Jerry Silver, associate professor of developmental genetics and anatomy, said: “Mouse callus hypoplasia (a form of congenital malformation of the corpus callosum that does not cross the midline of the brain) can be substantially healed.” To determine if a brain is present during development provides nerve fibers Nerve cell pathways, Silver has studied the corpus callosum for many years. There are several reasons for choosing a corpus callosum: First, it is bulky. It consists of about 300,000 fibers in mice and about 300 million fibers in the human body because it is easily accessible under the large blood vessels near the surface of the brain. This means we can reach it without damaging too much brain tissue. Second, there is a corpus
