Nature/Nurture

UNDERSTANDING HOW THE BRAIN DEVELOPS To understand how this happens, we need to understand a bit about how the principal casts. The wiz is comprised of many regions that work out specific functions, such as identifying what we see, makeing utter language, or assessing whether we be in danger. Within each of these brain argonas ar millions of neurons, or nerve cells, which send messages to each otherwise across synapses. These trillions of nerves and synapses and the pathways they form make up the fit of the brain; they allow all of the various areas to communicate and function in concert in a coordinated way. The reduce and organization of connections in the brain influence everything from the ability to have it off letters of the alphabet to mental quickness at managing labyrinthian social relationships. In most regions of the brain, no new neurons are formed after birth. Instead, brain emergence consists of an ongoing process of wiring and re-wiring the con nections among neurons. New synapses between cells are constantly beingness formed, maculation others are broken or pruned out. This happens throughout life. However, in early childhood the brain is genetically programmed to produce more than synapses than it will ultimately use. Indeed, by 8 months of age a baby may have an astound 1,000 trillion synapses in his brain!

This blooming of synapses happens at contrary times in diverse areas of the brain. Development then consequence by keeping the synapses that are used and pruning away those that arent. The pruning of synapses happens over the childhood year s as the different areas of the brain break! down (Huttenlocher & Dabholkar, 1997). Pruning allows the brain to keep the connections that have a purpose, while eliminating those that arent doing anything. In short, pruning increases the faculty with which the brain cigaret do what it needs to do. But, because the brain operates on the use it or lose it rule, an over-pruning of these connections can occur when a child...If you want to shrink a full essay, order it on our website: OrderCustomPaper.com
