呵呵，別怨嘆老爸老媽把你生的不夠聰明，
有賴醫學研究的發達，
看看這篇文章，
買些補充品，
自個兒補補腦吧。
這是ScienceDaily昨天update的文章，
同樣我也按段落給予翻譯，
並且再參考1月28日出刊的Neuron期刊。
各位參考參考嘍～～～

Magnesium Supplement Helps Boost Brainpower
補充鎂離子有利於增強大腦智能
New research finds that an increase in brain magnesium improves learning and memory in young and old rats. The study, published in the January 28th issue of the journal Neuron, suggests that increasing magnesium intake may be a valid strategy to enhance cognitive abilities and supports speculation that inadequate levels of magnesium impair cognitive function, leading to faster deterioration of memory in aging humans.
新研究發現，大腦內鎂離子的增高可以促進年青和老年大鼠的學習和記憶能力。這項研究發表在1月28日出刊的Neuron雜誌，意指增加鎂的攝取可能是一個提高認知能力的有效策略。研究結果也支持，缺乏鎂離子將導致認知功能損害，從而更快地惡化老年人的記憶化。
Diet can have a significant impact on cognitive capacity. Identification of dietary factors which have a positive influence on synapses, the sites of communication between neurons, might help to enhance learning and memory and prevent their decline with age and disease. Professor Guosong Liu, Director of the Center for Learning and Memory at Tsinghua University in Beijing, China, led a study examining whether increased levels of one such dietary supplement, magnesium, boosts brain power.
飲食可以顯著地影響認知能力。若能證實哪些飲食因素能夠正面的影響神經元突觸之間的溝通，將可能有助於提高學習和記憶，並防止其因為年老與疾病所造成的衰退。北京清華大學學習記憶中心主任，劉教授指出，中國目前正執領一個研究，探討提高『鎂』這樣一個的日常營養補充劑，是否能增進腦力。
註：領導這一研究的是清華大學醫學院劉國松教授，其2005年回大陸，入選清華大學『百人計劃』、『長江學者特聘教授』，受聘於清華大學醫學院擔任教授、博士指導。主要研究方向包括神經系統可塑性和神經系統網絡形成及優化的研究，和學習與記憶的基本原理研究及增強記憶和抗腦衰老的新藥開發。

"Magnesium is essential for the proper functioning of many tissues in the body, including the brain and, in an earlier study, we demonstrated that magnesium promoted synaptic plasticity in cultured brain cells," explains Dr. Liu. "Therefore it was tempting to take our studies a step further and investigate whether an increase in brain magnesium levels enhanced cognitive function in animals."
劉博士進一步解釋，『鎂』是身體器官組織正常運轉必不可少的元素，其中包括大腦。在以前研究中已證實，鎂能夠促進實驗室培養的腦細胞神經突觸可塑性。因此，這值得我們進一步研究，並探討增加腦中鎂離子濃度是否能提高動物認知功能。
註：正常情況下，人體內的鎂離子可以通過食物攝取獲得，許多天然食物，如南瓜子、海帶、菠菜、堅果等都富含鎂離子。然而，隨著工業化的進程，食物的精細加工導致食物中的鎂含量下降，以及飲食結構的變化導致老年人鎂攝入不足。

Because it is difficult to boost brain magnesium levels with traditional oral supplements, Dr. Liu and colleagues developed a new magnesium compound, magnesium-L-threonate (MgT) that could significantly increase magnesium in the brain via dietary supplementation. They used MgT to increase magnesium in rats of different ages and then looked for behavioral and cellular changes associated with memory.
因為傳統的口服補充劑很難提高腦中鎂的含量，劉博士和同事開發出一種新的鎂化合物，鎂基- L -蘇糖酸（MgT），可以通過飲食補充顯著地提高大腦中的鎂含量。他們以MgT餵食不同年齡大鼠，提高其腦中鎂含量，然後探討其與記憶有關的行為和細胞變化。

"We found that increased brain magnesium enhanced many different forms of learning and memory in both young and aged rats," says Dr. Liu. A close examination of cellular changes associated with memory revealed an increase in the number of functional synapses, activation of key signaling molecules and an enhancement of short- and long-term synaptic processes that are crucial for learning and memory.
我們發現，增加大腦中的鎂含量，能增強年輕和老年大鼠，許多不同形式的學習和記憶，劉博士指出。在深入研究下發現，與記憶相關的功能性突觸明顯增加，並且活化關鍵的訊息分子，從而加強短期和長期的突觸進程。而上述兩點正是對學習和記憶相當重要的過程。

The authors note that the control rats in this study had a normal diet which is widely accepted to contain a sufficient amount of magnesium, and that the observed effects were due to elevation of magnesium to levels higher than provided by a normal diet.
作者強調，在這項研究中對照組老鼠依然有正常的飲食，即平日有攝取足夠量的鎂，而實驗中觀察到的效應皆起因於實驗鼠攝取超過高於日常飲食的鎂。

(T形迷宮：測驗老鼠能否記得哪一邊有食物) "Our findings suggest that elevating brain magnesium content via increasing magnesium intake might be a useful new strategy to enhance cognitive abilities," explains Dr. Liu. "Moreover, half the population of industrialized countries has a magnesium deficit, which increases with aging. This may very well contribute to age-dependent memory decline; increasing magnesium intake might prevent or reduce such decline."
劉博士解釋說，研究結果顯示，通過增加鎂的攝取量，以提升大腦鎂含量，可能是一個有用的新策略，來增進認知能力。此外，工業化國家裡往往有一半的人口屬於鎂攝取不足者，這將加速老化，導致記憶力伴隨著年齡增加而下滑。因此增加鎂的攝取量也可能阻止或減少退化情形。
