Question

Quizplus · Accepted Answer

In the first year of life, brain development emphasizes the formation of synapses. This is critically important as synapses allow neurons to communicate with each other, forming the basis of all cognitive functions. While the development of neurons and glial cells is also important, it is the formation of synapses that underlies the most rapid and dramatic changes in brain structure and function during this period. Synapto-atrophy (the pruning of unused synapses) occurs later in development and is not a major emphasis in the first year of life. A proximodistal pattern (development from the center of the body outward) is seen in the growth of some structures during fetal development, but is not as relevant to postnatal brain development.
