A team of scientists has come up with evidences show that we can improve vocabularies, and even learn a foreign language while sleeping, according to the British newspaper “Daily Mail”.
The new thing discovered by the team of scientists at the University of Bern in Switzerland is that the human brain can process data while sleeping.
The scientists also found that sleeping contributes to the improvement and integration of words and information saved in the brain, the thing that facilitates remembering them through awakening. Remarkably, scientists have found that foreign words and their translations can be studied during sleep.
Participants can easily find the meaning of the word in comparison with those who have not undergone the experiment of programming the brain during sleep.
The new study is likely to explain that the “Hippocampus”, “which is a cerebral structure essential for developmental learning”, helps to “awaken” the human brain to reach new words that are newly learned.
The researchers have tested the participants to see whether the sleeping person can form new links between
foreign words and their translations during the active status in brain cells, called “advanced states”. The “inactive state” is called “low state”. The two states alternate almost each half a second.
When the human go into the stage of deep sleep, the brain cells gradually coordinates between the activity of both states.
During sleep, the brain cells are active for a short time before altogether entering in a state of short inactivity.
Dr. Mark Zust, the head of research team, says: “it was found that links between words are stored and saved, so when audio recordings for a language are played during sleep and translated into German language, only the second word will be saved if only the translated meaning of the word is recorded frequently during “advanced state”.
Dr. Zust further explains: “interestingly enough that the language areas in the brain and hippocampus – the brain basic memory axis – have been activated during the retrieval of vocabularies learned during sleep, because these areas of the brain structure have the mediation role when learning new vocabularies.
It seems that these parts of the brain mediate memory formation independently of the prevailing state of consciousness – and unconsciousness during deep sleep, and these parts are conscious during awakening”.
