By age 8 to 10,__________.
A) energy metabolism in the cerebral cortex peaks
B) the number of synapses in the prefrontal cortex is nearly half the adult value
C) energy consumption of most cortical regions diminishes to near-adult levels
D) brain size increases to about 70 percent of its adult weight

Question

Quizplus · Accepted Answer

Energy consumption of most cortical regions diminishes to near-adult levels by age 8 to 10. This is due to the fact that the brain undergoes a pruning process during which it eliminates unnecessary synapses and strengthens important ones, resulting in more efficient neural processing. As a result, the brain requires less energy to perform the same tasks.
