A normal brain is not a particular network pattern but one that can reconfigure itself with experience.
Scientists have recognized for decades that children’s brains change as they develop and learn. Neurons or the nerve cells that make up our brains, receive stimulus from the world through the senses and are constantly growing out long extensions or cables in search of one another to form connections. These connections, called synapses, largely arise or strengthen when the neurons are sharing information or are active during the same stimulus. Cells that carry related information, therefore, become more strongly connected than those that carry unrelated information. Children are born with many more neurons and synapses than adults, initially arranged in a loose and imprecise network.
