英《新科学家》1981年8月20日一期报道:基因如何控制神经系统的发育?变异型动物的大脑常常是异常的,可以提供线索。但是,遗传方面的缺陷是直接影响个体细胞呢?还是改变了细胞生长的环境? 耶鲁大学的赫拉普(Karl Herrup)和犹他大学的马伦(Richard Mullen)一直在研究突变种蹒跚病小鼠的发育。这些小鼠的小脑异 British “New Scientist” August 20, 1981 A report: How Gene Controls the Development of the Nervous System? The brain of mutant animals is often abnormal and can provide clues. But are genetic defects directly affecting individual cells or changing the environment in which cells grow? Karl Herrup of Yale University and Richard Mullen of the University of Utah have been studying mutant white-spotted mice Development. The cerebellum of these mice is different
