The latest research has discovered that even in sleep the brain is comparatively active and is capable to recall simple words that you may have read before sleep, but the unconscious condition during sleep stopped them from reacting (no movement of the fingers).
The test explains that a few parts of the brain perform the same whether asleep or awake, this experiment was recently conducted by scientists from Paris and the University of Cambridge and detail report on the research was published in Cell Press journal Current Biology.
The test demonstrated that when people were focused on easy word sorting tasks before sleeping, the brain prolongs to automatically make categorizations those words, even in sleep so this study is a step toward understanding the huge unused prospective of the human brain, say researchers.
The researcher Sid Kouider said in a press release that “we explain that the sleeping brain can be extremely more ‘active’ in sleep than one would think and far from falling [into] a limbo when we fall asleep, parts of our brain can normally progression what is going on in our surroundings and give a proper method of the response. This theory further elaborates a few everyday life experiences such as an extreme sensitivity to a person’s name during his sleep, or to the particular tone of own alarm clock, compared to equally loud but less related sounds.”
In the experiment, their EEG was also simultaneously recorded while the contestants were asked to classify easy words belonging to one of the two categories such as animals or things by pressing a button with the right hand for animals and with the left for objects. After that the contestants kept in a dark room by the researcher to lie down cheerfully with eyes closed and keep on the word classification task as they drifted off to sleep.
Formerly the contestants were asleep; the testing continued, but with a completely new catalog of words to make sure those responses would need the extraction of word meaning rather than a simple pairing between motivation and response. The investigator’ studies of brain activity explained that the contestants continued to react perfectly, although slower than when they were awake.
