This article on brain development provides a simplified version of the subject. The process of brain development is much more complex and complicated than depicted, particularly for humans. Familial and social environment has been increasingly implicated in the development of the human brain, both structurally and functionally. Indeed, children raised in an enriched environment do better on intelligence tests than children raised under the same nutritional regime but in a poorer environment. Heredity is another important determinant in brain development.
The whole human situation is extremely complex, compounded by intricate interactions between nutrition, environment, and heredity on the overall development of physical and mental health. The brain stands in the center of this complex milieu, and, as noted by John Eccles, a great pioneer in brain research, we must continue to use our brains to understand how they show plasticity toward these and other possible factors to attain the ultimate potentiality of the development and function of our brains.
