- Can you recall the taste when your mother breast-feeding you? If no, what is the earliest thing you can remember about yourself? The question is: when do we started to understanding and analyzing this world by ourselves? Brain can be impacted by the differences of age, environment, gender, connectivity, etc.
- Here is an interesting point: One’s early life stress would impact his brain effectively, in the other word, it is the most effective pattern. Previous institutionalization is one common brain stimulation in early life. Memories and Emotions are more vulnerable
- Brain development continues for an extended period postnatally. The brain increases in size by four-fold during the preschool period, reaching approximately 90% of adult volume by age 6 (Reiss et al. 1996; Iwasaki et al. 1997; Courchesne et al. 2000; Kennedy and Dehay 2001; Paus et al. 2001; Kennedy et al.2002; Lenroot and Giedd 2006). But structural changes in both the major gray and white matter compartments continue through childhood and adolescence, and these changes in structure parallel changes in functional organization that are also reflected in behavior. During the early postnatal period, level of connectivity throughout the developing brain far exceeds that of adults (Innocenti and Price 2005). This exuberant connectivity is gradually pruned back via competitive processes that are influenced by the experience of the organism. These early experience dependent processes underlie the well-documented plasticity and capacity for adaptation that is the hallmark of early brain development. (Extension of Human Brain)
As the article says that human brain only develops efficiently before the age of 6 and decreasing from that point. But most successful people in academic field with young ages kept their brain advancing longer than 9 years by training brain in daily life such as memorizing and deeply thinking.
- The Organization of the Mature Brain The human brain is arguably the most complex of all biological systems. The mature brain is composed of more than 100 billion neurons (Pakkenberg and Gundersen 1997).Neurons are the information processing cells in the brain. There are many different kinds of neurons that vary in their size and shape as well as in their function. Neurons make connections with other neurons to form the information processing networks that are responsible for all of our thoughts, sensations, feelings and actions. Since each neuron can make connections with more than 1,000 other neurons, the adult brain is estimated to have more than 60 trillion neuronal connections. (Mature Brain)
- There are too little things to let human know after age of six. In other words, too little interest. People get used to this world in the first six years and mentally stopped themselves from exploring the reality of this world. It is the reason that I can think of why there is a limit of efficiency of brain development. After age of 25, human brain does not have more capability of growing any longer, therefore people would act and react the ways like mature most likely.
- Human beings use their brains though entire life. When it claims that our brains stopped developing at the age of 25, I would not believe that. Most knowledgeable people in the world are the elderly and how could they accomplish those achievements if their brains stopped growing at such an early age?
