Nature/Nurture

UNDERSTANDING HOW THE BRAIN DEVELOPS To understand how this happens, we need to understand a bit about how the principal prepargons. The intelligence is comprised of many regions that work out specific operate ons, such as identifying what we see, treating utter language, or assessing whether we be in danger. Within each of these brain argonas are millions of neurons, or nerve cells, which send messages to each another(prenominal) across synapses. These trillions of nerves and synapses and the pathways they form make up the fit out of the brain; they allow all of the various areas to communicate and function in concert in a coordinated way. The depend and organization of connections in the brain influence everything from the ability to endorse letters of the alphabet to mental quickness at managing hard 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 an d re-wiring the connections among neurons. New synapses between cells are constantly world formed, plot of ground 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 retention the synapses that are used and pruning away those that arent. The pruning of synapses happens ev eryplace the childhood years as the differen! t areas of the brain generate (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 stern 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 personate a full essay, order it on our website: OrderCustomPaper.com
