How to become smarter in the coming year? This will help new scientific achievements, says The Daily Beast .Scientists make practical recommendations that can be easily performed in everyday life, but, alas, dispel the myths about food, which supposedly strengthens the intellect, says journalist Sharon Begley.
The most promising – the discovery that an IQ can be improved. “It was long thought that early childhood IQ remained more or less unchanged,” – reminiscent of the author. However, if you believe the article in Nature, IQ for four years, could grow by 21 points or decrease by 18. The difference is huge: for example, 110 points – it’s “average intelligence”, and 130 – “talent,” explains Katie Price at the University College London, who led the research.
The studies involved persons Price 12-20 years. However, the very Price believes that the results of her research are valid for all ages. The fact is that recently scientists have discovered that the brain characteristic of “neuroplasticity” creates new neurons even in the age of 60-70 years.
In this regard, the author recalls that the improvement in the sensory-motor skills may improve cognitive. “Learn to knit, to understand classical music or juggle: probably because you increase your IQ”, – she advises.
Another unexpected discovery was made in 2008: it turns out, short-term memory – support the general level of intelligence. Scientists led by Suzanne Dzheggli University of Michigan, trained adult volunteers to perform a difficult task for the development of short-term memory. The longer the participants practiced, the better their ability to think logically and solve problems.
Another way to raise IQ – to improve the brain’s ability to focus, recommends publication. Some drugs help-stimulants, which increase dopamine levels. According to researchers, the memory and the ability to switch attention to developing the gamers. Helps and passionate interest, according to Katie Price: If you are indifferent to the fact that reading, see or hear, it will be erased from your memory.
According to the newspaper, to train the brain is not so difficult. “The 30-minute walk 5 times a week stimulates protein BDNF – brain-derived neurotrophic factor, which is fueling the creation of new neurons and synapses in the process of learning” – the article says.
Naps after jobs tiring hippocampus, do not just restore mental capacity, but also can improve them, psychologist Matthew Walker found and his colleagues at the University of California at Berkeley. Nike and Google rightly so, that give employees a special room for “quiet hours”, the author notes. Walker reasoned that the hippocampus during sleep carries information in long-term memory. As a result, information is better remembered, and the ability to receive updated information improves.
Even without a siesta brain finds a way to relax – indulges in reveries, or ceases to think. Scientists from Japan’s Tohoku University have found: the more actively the blood supply to the “white cell” of the brain at rest, the faster and better person provides innovative ideas, the magazine writes, referring to an article in the November issue of PLoS One. “Put the phone and give your brain pobezdelnichat” – suggests the author.
To increase the penetration is caffeine, according to a study published in Nature Neuroscience. In rats after injections of caffeine are more active connection of neurons in the hippocampus, which improves learning and memory.
The most-tested strategy – at the same time the most difficult: to learn a foreign language. Fluency in two languages ??prefrontal cortex induces more effort, which improves the ability to solve problems and to switch attention and pulls a 5-year occurrence of senile dementia, found Ellen Byalistok of York University (Canada).
Is there a special diet for poumneniya? Alas, in 2010, researchers at the Duke Evidence-Based Practice Center have concluded that many of the vaunted recipes do not work. Nutritional supplements with vitamins B6, B12 and E, and folic acid does not affect the preservation of cognitive functions, let alone improve them. The Mediterranean diet (fish, fruits, vegetables, olive oil) also yields nothing. However, there is evidence that turmeric and pomegranate juice may improve memory or other cognitive functions.
Based on the foregoing, the magazine formulates recipe poumneniya “mnemonic exercise, caffeine flavor, interspersed with healthy sleep, and aerobic exercises to improve attention to the computer, reading, watching and working with a long break for the rest of the brain.”
