KUSA - A new study by CU-Boulder found while children sleep, the connections between the left and right sides of their brains strengthen.
Researchers used EEGs to measure brain activity of eight sleeping children at various times while they were 2 years old, 3 years old and 5 years old.
They found the strength of the connections between the two hemispheres went up by as much as 20 percent over a night's sleep.
What researchers have not found yet is how sleep leads to changes in the brain structure.
Future studies will try to figure out how sleep disruption during childhood may affect brain development and behavior, including developmental or mood disorders.
