The influence of alpha waves in the memory (article)

[html]<p> it is Well known that the ability to remember events, their time and place weakens with age. </p>
<p>Interestingly, the power of the alpha rhythms of the brain also decreases with age, while there is a clear line of weakening the alpha rhythms of the emergence of diseases such as, for example, Alzheimer's disease.</p>
<p> This is very important, because theoretically, the alpha wave is closely associated with the encoding of certain types of memory. Recently very well known that drugs used to modulate the slow rhythms of the EEG activity that can really improve memory. </p>

<p>modern research has shown that brain stimulation by flashes of light gives even better results in this area and offers tremendous opportunities to address age-related memory problems in total abstinence from drugs.</p>
<p> In the journal <em>BMC </em><em>Neuroscience</em> (Neuroscience) was published showing that the flash frequency of 10 Hz used in the process perform complex tasks on a memory test, have been very promising. Executing tasks to test their memory the most age participants of the project led to the expected low results, appropriate to their age. </p>
<p>But if you are using alpha-stimulation has become evident that the results of the assignment began to match the level of young people!</p>
<p><strong>Used</strong><strong> method</strong> <br>
Unlike other effects, produce audio-visual stimulation, alpha stimulation is very specific. The difference between the frequency of outbreaks only 0.5 Hz gives results ranging from a positive effect to completely zero. </p>

<p class="disc">10 Hz and 10.2 in the article seem “magical” frequencies.</p>
<p> Also interesting is the duration of the flares: only 1 second! Participants were asked to memorize words that appear on the screen. Before the advent of each portion of the words, participants were submitted to 1-second flash rate of 10 Hz alpha stimulation by LEDs installed in the peripheral field of view.</p>
<p><strong>Why is such a brief period of stimulation gives a positive effect?</strong> <br>
This study suggests that the involvement of alpha waves in the natural process of memory formation it takes a very short period of time. </p>
<p>alpha waves synchronized in a very short period of time. It is theorized that the flash alpha stimulation enhances the effect of synchronization, which leads to improved memory.</p>
<p>the Hippocampus, which is involved in memory formation, perhaps, is the structure of the brain, allowing this effect. There are the obvious facts that the slow waves of the type observed in the hippocampus, facilitate the process of memory formation.</p>
<p> on the other hand, the study also noted that the duration of the pause between flashes is very short, so the effects of alpha waves are transmitted from one portion of the material to remember to the other. The effects of longer periods, as long-term effects of alpha stimulation, is still subject to scrutiny. And yet this very promising method, especially given the results of other studies, demonstrates a sustainable and long-lasting effect of alpha stimulation.</p>

<p><strong>More interesting facts about this study:</strong></p>
the <ul>
the <li>, the effect of the flares is not retroactive. In other words, improvements in memory were observed only AFTER the outbreak. The facts encoded in the memory until the moment of stimulation, its consequences not exposed.<br / >
<br / >
</li>
the <li>the brightness of the LEDs has a relationship with the strength of the effect. The brighter the led, the more powerful effect on strengthening memory.<br>
<br / >
</li>

the <li>Effects improve memory the most profound in older adults, but previous studies have demonstrated that alpha stimulation also gives improve memory in young!<br>
<br / >
</li>
the <li>Also, some previous studies showed that theta stimulation improves memory, and after studying the material to be remembering.<br>
<br / >
</li>
the <li>above all, this study glad that the LEDs are located on the sides of the eyes, not in plain sight. In fact, most of the participants didn't even notice them!</li>

</ul>
<p>It's inspiring for the further study of points of the open eye (glasses eyes).<br>
