B)Are most prevalent during the 8th-15th week of gestation,the typical time of proliferation and migration
C)Are most prevalent after the 15th week of gestation,during circuit formation and circuit pruning

Question

Quizplus · Accepted Answer

During the 8th-15th week of gestation, the brain is in the stage of proliferation and migration, and it is the time when the developing brain is most vulnerable to the effects of ionizing radiation. The cells are rapidly dividing and migrating to form the different parts of the brain. Any disruption during this critical period can lead to malformation, abnormal growth, or cell death, resulting in long-term neurological deficits.
