New Perspectives on Early Brain Development Connections that aren't produced by activity, or are weak, are "pruned away," much like the pruning of dead or weak branches of your tree. If the neurons are utilized, they become incorporated into the circuitry of the brain. Due to differences in experience, not even alike twins are wired exactly the same. The main basis for the significance to move and sensory experiences was derived from studies which compared brain structures of animals raised in various environmentally normal, deprived, and improved settings. The improved settings provided the ability to interrelate with toys, treadmills, and obstacle courses. Implications for the Early Childhood Educator. One from the strongest implications of brain researchers have been the identification of grave periods in brain increase in which experience might be handiest in forging relations in wiring mental performance. Studies with small children using modern neuroimaging, pictures
