Synaptic prune - Essay Example114). Researches kick in shown that in that location is a direct relation of synaptic pruning with change in brain size. As the synapses halt reduced, the size of the brain reduces by a small fraction (Paus et al., 2008). But that is not all of which occurs as a result of synaptic pruning. The neurons that get activated and the synapses that are utilized more and more range to grow and their myelination occurs. Myelin, a fatty substance, gets coated on the neural axons so that they are protected. This also developments their transmission system speed (Feldman, 2010, p. 114). The growth of the neurons is much faster than the dying away of the unused neurons, which causes a large increase in brain size during the first 2 years after birth. This has been backed by magnetic resonance imaging scans (Paus et al., 2008).Synaptic pruning has been associated with the capacity of glucose metabolism as well as age related changes, save that is not the case (Paus et al., 2008). Rather, changes in the size of grey matter are affected by pruning and myelination of the white matter. T1-weighted images film been used to prove this trend (Paus et al., 2008).It has been observed that the brain development in the initial stages can cover up for certain injuries to the brain because other areas can take over for the hurt area. This is not so for adult brains, for which it is hard to recover from a mental injury (Feldman, 2010, p. 114).Researches on non-humans have shown a strong relation between synaptic pruning and the plasticity of a human brain. malleability refers to the degree to which a brain is modifiable due to experience. For very young babies, the plasticity of the brain is at its peak. This means that they have a very high ability to learn new things. It also indicates that they have a higher tendency to be influenced by the environment around them. Studies are trying to tell apart this
