Document Summary
Brain grows very rapidly the top to the bottom. Cephalocaudal development - development of the nervous system starts at. Proximodistal development - development starts in the middle of the body and moves outward to the extremities. Babies make more connections as they grow. Removing some of the connections that aren"t needed to make transmission more efficient. Brain is able to adapt to changing environments. Myelin: insulating layer of proteins and fatty substances. As you grow, myelin sheath covers more axons. Sucking, withdrawal from pain, closing eyes for light. Controlled by more primitive parts of the brain: medulla/midbrain. Prompt attention to crying in the first 3 mos. leads to less crying later. Some suggest babies should not watch tv before age of 2. Rapid growth in first 2 years leads to stamina and sustaining motor activity. Environment plays a role; not only abilities. Nutritionally superior: more rapid weight gain and size. May not be possible for some mothers.
