The incredible brain growth that we see in the first 2 years of life is,at least in part,attributable to
A) neurogenesis.
B) increased cerebrospinal fluid.
C) growth of synapses.
D) decreased myelination.

Question

Quizplus · Accepted Answer

The growth of synapses is a significant factor in the incredible brain growth seen in the first 2 years of life. In this period, the brain experiences a rapid increase in the number of connections between neurons as synapses are formed, leading to an increase in brain size and complexity.

Answer options A, B, and D are incorrect because neurogenesis (the development of new neurons), increased cerebrospinal fluid, and decreased myelination do not account for the significant brain growth observed in the first 2 years of life.
