Brain development along life

Scientific evidence shows that the brain continues to develop into adulthood and not only during the first years of life. It is true that in early childhood there is a large increase in neural connections (synapses) and the rate at which these synapses are set decreases with age.Similarly,the rate of synaptic pruning (removal of neuronal connections that are rarely used) is greater during childhood, encouraging greater efficiency of connections that remain. However, these two processes continue to be carried into adulthood, especially in those areas of the brain necessary for learning more, allowing it can build throughout life.

Therefore, the vast majority of learning can be acquired throughout life in environments with a stimulus and a proper education.

It has been much talk about the importance of early stimulation for the development of synapses and learning. However, study results say more about the negative effects of a private environment of positive stimulation of an enriched environment. It is for this reason that children who have been abandoned or neglected show delays or deficits in cognitive development. There is evidence, therefore, that impoverished inhibit neuronal development environments but not the enriched enhance it. It can be expected, therefore, that children who have grown up in an environment also have good potential to learn.

During adolescence the brain presents a major development, especially in areas where carried out the most complex cognitive processes, the temporo-parietal-occipital cortex and prefrontal cortex. In these brain regions neuronal pruning does not start until puberty. Also during this stage there is also an increase in myelination in these brain areas. Myelination is a process by which nerve fibers are coated with a lipid substance called myelin, allowing faster communication of information. By improving the efficiency of neuronal communication more complex cognitive processes are favored and that is why during puberty began to develop the most abstract formal thought. During the years of adolescence, therefore, a reorganization of the brain occurs. Since the brain is still developing during this stage, it is important to continue to secondary and higher education in order to mold it into a more efficient operation.

The brain continues to develop in adulthood. As he grows older, however, it becomes less plastic and neurons are lost at a faster rate.However, it is still not well understood the impact this has on learning loss. Furthermore, no evidence of neurogenesis (playback neurons) in a sector of the brain, the hippocampus area of great importance for learning and memory. Brain plasticity throughout adulthood suggests that it is well designed for continuous learning and adapting to new situations and experiences. New learning and adaptations can stimulate significant changes in brain structure.

We can conclude that humans have the ability to learn throughout our lives.Similarly, the brain is constantly developing thanks to its plasticity in normal health. We must seize this great potential not only in children but also in us as adults.
