2015年哈佛大学语言专家Gigi Luk 副教授最新研究显示小的时候双语成长，能在大脑发育的阶段给脑部带来很多有益的帮助。以前大家认为双语会带来脑部混乱， 最新 研究显示，对比单一语言使用者来说， 如果一辈子都说两种语言的人年老了以后大脑前头叶（frontal lobes， 推理，问题解决功能）能够有更多的white matter， 负责语言的 侧头叶（temporal lobes）也可到更多的保护。 所以这是结论有力地支持了双语使用对脑部物理和功能的作用。

超越实验室评论：投资孩子是最好的投资，现在更有理由把我们孩子的双语教学放到最重要的位置！

BILINGUALISM AND THE AGING BRAIN

Luk and her researchers are looking at the neuroscience of bilingualism — at how bilingualism may affect the physical structure of the brain in its different regions.

What they’ve found so far shows that older adults who are lifelong bilinguals have more white matter in their frontal lobes (important to executive function) than monolinguals, and that their temporal lobes (important to language function) are better preserved. The results support other evidence that persistent bilingual experience shapes brain functions and structures.

A growing body of evidence suggests that lifelong bilingualism is associated with the delayed diagnosis of dementia. But the impact of language experience on brain activity is not well understood, Luk says.

In a 2015 paper, she and her colleagues began to look at functional brain networks in monolingual and bilingual older adults. Their findings support the idea that a language experience begun in childhood and continued throughout adulthood influences brain networks in ways that may provide benefits far later in life.
