The First Year of Life Represents An)

Question

The first year of life represents an)
A) Slow-to-mature pattern of brain growth
B) Uneven pattern of brain growth, with sensory regions developing before frontal lobe regions
C) Equally rapid brain growth in all regions of the cortex
D) Mostly subcortical development, since cortex starts to grow only in the third year of life

Accepted Answer

During the first year of life, brain growth follows an uneven pattern, with sensory regions and areas involved in basic functions developing before those regions responsible for more complex functions, such as the frontal lobes. This reflects the principle of cephalocaudal and proximodistal development, where growth and development proceed from the head downward and from the center of the body outward, respectively.
