                              Can you learn in your sleep?


          Sleep is known to be crucial for learning and memory formation. What's more, scientists have even managed to pick out specific memories and consolidate them during sleep. However, the exact mechanisms behind this were unknown — until now.

          Those among us who grew up with the popular cartoon "Dexter's Laboratory" might remember the famous episode wherein Dexter's trying to learn French overnight. He creates a device that helps him to learn in his sleep by playing French phrases to him. Of course, since the show is a comedy, Dexter's record gets stuck on the phrase "Omelette du fromage" and the next day he's incapable of saying anything else. This is, of course, a problem that puts him through a series of hilarious situations.

          The idea that we can learn in our sleep has captivated the minds of artists and scientists alike; the possibility that one day we could all drastically improve our productivity by learning in our sleep is very appealing. But could such a scenario ever become a reality?

          New research seems to suggest so, and scientists in general are moving closer to understanding precisely what goes on in the brain when we sleep and how the restful state affects learning and memory formation.

          For instance, previous studies have shown that non-rapid eye movement (non-REM) sleep — or dreamless sleep — is crucial for consolidating memories. It has also been shown that sleep spindles, or sudden spikes in oscillatory brain activity that can be seen on an electroencephalogram (EEG) during the second stage of non-REM sleep, are key for this memory consolidation. Scientists were also able to specifically target certain memories and reactivate, or strengthen, them by using auditory cues.

          However, the mechanism behind such achievements remained mysterious until now. Researchers were also unaware if such mechanisms would help with memorizing new information.

          Therefore, a team of researchers set out to investigate. Scott Cairney, from the University of York in the United Kingdom, co-led the research with Bernhard Staresina, who works at the University of Birmingham, also in the U.K. Their findings were published in the journal Current Biology.

          Cairney explains the motivation for the research, saying, "We are quite certain that memories are reactivated in the brain during sleep, but we don't know the neural processes that underpin this phenomenon." "Sleep spindles," he continues, "have been linked to the benefits of sleep for memory in previous research, so we wanted to investigate whether these brain waves mediate reactivation. If they support memory reactivation, we further reasoned that it could be possible to decipher memory signals at the time that these spindles took place."

          To test their hypotheses, Cairney and his colleagues asked 46 participants "to learn associations between words and pictures of objects or scenes before a nap." Afterward, some of the participants took a 90-minute nap, whereas others stayed awake. To those who napped, "Half of the words were [...] replayed during the nap to trigger the reactivation of the newly learned picture memories," explains Cairney.

          "When the participants woke after a good period of sleep," he says, "we presented them again with the words and asked them to recall the object and scene pictures. We found that their memory was better for the pictures that were connected to the words that were presented in sleep, compared to those words that weren't," Cairney reports.

          Using an EEG machine, the researchers were also able to see that playing the associated words to reactivate memories triggered sleep spindles in the participants' brains. More specifically, the EEG sleep spindle patterns "told" the researchers whether the participants were processing memories related to objects or memories related to scenes.

          "Our data suggest that spindles facilitate processing of relevant memory features during sleep and that this process boosts memory consolidation," says Staresina. "While it has been shown previously," he continues, "that targeted memory reactivation can boost memory consolidation during sleep, we now show that sleep spindles might represent the key underlying mechanism."

          Cairney adds, "When you are awake you learn new things, but when you are asleep you refine them, making it easier to retrieve them and apply them correctly when you need them the most. This is important for how we learn but also for how we might help retain healthy brain functions."

          Staresina suggests that this newly gained knowledge could lead to effective strategies for boosting memory while sleeping.

          So, though learning things from scratch à la "Dexter's Lab" may take a while to become a reality, we can safely say that our brains continue to learn while we sleep, and that researchers just got a lot closer to understanding why this happens.

    Another finding of the research is related to the electroencephalogram (EEG) that was done while the participants were sleeping and exposed to the replay of the words, which revealed

          So, though learning things from scratch à la "Dexter's Lab" may take a while to become a reality, we can safely say that our brains continue to learn while we sleep, and that researchers just got a lot closer to understanding why this happens.

    Atente para o seguinte trecho de um artigo de jornal: “Segundo o coordenador do Setor de Ciências Naturais e Sociais da Unesco no Brasil, Fabio Eon, os direitos humanos estão sendo alvo de uma onda conservadora que trata a expressão como algo politizado. — ‘Existe hoje uma tendência a enxergar direitos humanos como algo ideológico, o que é um equívoco. Os direitos humanos não são algo da esquerda ou da direita. São de todos, independentemente de onde você nasceu ou da sua classe social. É importante enfatizar isso para frear essa onda conservadora’ — ressalta Eon, que sugere um remédio para o problema: — ‘Precisamos promover uma cultura de direitos humanos’”.

    A Declaração Universal dos Direitos Humanos foi aprovada pela Assembleia Geral da ONU em 1948. Já a Declaração dos Direitos do Homem e do Cidadão foi aprovada durante a primeira fase da Revolução Francesa, pela Assembleia Nacional Constituinte.

    Leia atentamente a seguinte passagem:


    “A experiência parece um pouco semelhante à ciência (epistéme) e à arte (tékhne). Com efeito, os homens adquirem ciência e arte por meio da experiência. A experiência, como diz Polo, produz a arte, enquanto a inexperiência produz o puro acaso. A arte se produz quando, de muitas observações da experiência, forma-se um juízo geral e único passível de ser referido a todos os casos semelhantes” (Aristóteles, Metafísica, 981a5).


    Com base no texto acima, considere as seguintes afirmações:


    I. Somente a ciência é conhecimento universal, cujos juízos gerais se aplicam a todos os casos semelhantes.

    II. A tékhne é uma forma de conhecimento universal, pois, com base nas experiências, se forma um juízo geral.

    III. Por ser semelhante à experiência, a tékhne não constitui um conhecimento universal.

    IV. A experiência é pressuposto dos conhecimentos universais (tékhné e epistéme), mas não é ainda um conhecimento universal.

    Atente para as seguintes citações:


    “Temos assim três virtudes que foram descobertas na nossa cidade: sabedoria, coragem e moderação para os chefes; coragem e moderação para os guardas; moderação para o povo. No que diz respeito à quarta, pela qual esta cidade também participa na virtude, que poderá ser? É evidente que é a justiça” (Platão, Rep., 432b).


    “O princípio que de entrada estabelecemos que se devia observar em todas as circunstâncias quando fundamos a cidade, esse princípio é, segundo me parece, ou ele ou uma de suas formas, a justiça. Ora, nós estabelecemos, segundo suponho, e repetimo-lo muitas vezes, se bem te lembras, que cada um deve ocupar-se de uma função na cidade, aquela para a qual a sua natureza é mais adequada” (Platão, Rep., 433a).


    Considerando a teoria platônica das virtudes, escreva V ou F conforme seja verdadeiro ou falso o que se afirma a seguir:


    ( ) Nessa teoria das virtudes, cada grupo desenvolve a(s) virtude(s) que lhe é (ou são) própria(s).

    ( ) Só pode ser justa a cidade em que os grupos que dela participam e nela agem o fazem de acordo com sua natureza.

    ( ) Quando sabedoria, coragem e moderação se realizam de modo adequado, temos a justiça.

    ( ) Existe uma relação entre a natureza dos indivíduos, o grupo de que devem fazer parte na cidade, as virtudes que lhes são adequadas e, em consequência, a função que nela devem desempenhar.

    “A liberdade do homem em sociedade consiste em não estar submetido a nenhum outro poder legislativo senão àquele estabelecido no corpo político mediante consentimento, nem sob o domínio de qualquer vontade ou sob a restrição de qualquer lei afora as que promulgar o poder legislativo, segundo o encargo a este confiado”.

    Considerando a definição de liberdade do homem em sociedade, de John Locke, atente para as seguintes afirmações:


    I. A concepção de liberdade do homem em sociedade de Locke elimina totalmente o direito de cada um de agir conforme a sua vontade.

    II. A concepção de liberdade do homem em sociedade de Locke consiste em viver sob a restrição das leis promulgadas pelo poder legislativo.

    III. A concepção de liberdade do homem em sociedade de Locke consiste em viver segundo uma regra permanente e comum que todos devem obedecer.
