As the child【12】, cells reach out and set up pathways to other cells needed to determine a【13】. For instance, the neurons in the eye send branches to the【14】cortex, which interprets【15】eye sees and, via other branches,【16】the person to react to what is seen. Each time an experience is repeated, the【17】are strengthened.
The first two years of life are an explosion of brain【18】and connections. By age two the【19】has more than 300 trillion connections. At the same time, cells that aren’t being connected or used are being【20】.
