Question

Quizplus · Accepted Answer

Neuronal migration occurs 6 to 24 weeks after conception. Choice A is incorrect because closure of the neural tube is a separate process that occurs around day 27. Choice B is incorrect because birth defects such as anencephaly and spina bifida are caused by incomplete closure of the neural tube during development, not neuronal migration. Choice C is incorrect because the peak rate of neuronal generation is closer to 250,000 neurons per minute.
