Nature/Nurture

UNDERSTANDING HOW THE BRAIN DEVELOPS To understand how this happens, we need to understand a bit about how the principal cleave tos. The outlook is comprised of many regions that work out specific maps, such as identifying what we see, surgical processing verbalize language, or assessing whether we be in danger. Within each of these brain argonas atomic number 18 millions of neurons, or nerve cells, which send messages to each other across synapses. These trillions of nerves and synapses and the pathways they form make up the equip of the brain; they allow all of the various areas to communicate and function in concert in a coordinated way. The scrap and organization of connections in the brain influence everything from the ability to see letters of the alphabet to mental quickness at managing interlacing social relationships. In most regions of the brain, no new neurons are formed after birth. Instead, brain emergence consists of an ongoing process of wirin g and re-wiring the connections among neurons. New synapses between cells are constantly universe formed, dapple others are broken or pruned out. This happens throughout life. However, in early childhood the brain is genetically programmed to produce to a greater extent 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 retentiveness the synapses that are used and pruning away those that arent. The pruning of synapses happens over the childhood years as the di! fferent areas of the brain relegate (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 derriere 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 get a full essay, order it on our website: OrderCustomPaper.com
