Question

Quizplus · Accepted Answer

The prefrontal cortex undergoes especially rapid pruning of synapses during the preschool and school years, leading to increased cognitive control and executive functions. It does not reach an adult level of synaptic connections during the first two months of life, nor is it responsible for body movement over the first year of life. It also develops after other cortical regions.
