The ________ during childhood results in a reduction in density of nerve cells, thus increasing the brain's efficiency.
A) significant increase in the number of neuronal connections
B) underdevelopment of frontal cortical systems
C) decrease in white matter
D) pruning of unused dendritic connections

Question

Quizplus · Accepted Answer

The process referred to is "pruning," where unused dendritic connections in the brain are eliminated, which helps in increasing the brain's efficiency by reducing the density of nerve cells. This natural process occurs during childhood and adolescence, allowing for a more efficient neural network by removing less-used connections.
