Question

Quizplus · Accepted Answer

During the fetal period of development, the central nervous system becomes active and begins to regulate essential functions such as heart rate and breathing. This is controlled by the brainstem, which develops early in fetal development. While synapses do decrease in number during early brain development, it is not a major change that occurs during the fetal period. There is no process of regeneration or decrease in the number of neurons during this time.
