Quizplus · Accepted Answer

The key developments of the brain in the first two years include the growth of the myelin sheath and the formation of dendrite connections, which allow for efficient communication within the brain. These developments are critical for cognitive and motor development, and they are shaped by both genetics and environmental factors.
