The brain volume significantly expands over the first 9 months after a human is born. What is most likely responsible for this change in brain volume?

Question

Quizplus · Accepted Answer

The significant expansion of brain volume in the first 9 months after birth is primarily due to the increased number of glia cells and the formation of myelin. Glia cells support and protect neurons, while myelination helps in the efficient transmission of neural signals, both contributing to brain volume increase.
