This is why it is hard to Remember When Waking Dreams

Jakarta , caught a glimpse of a beautiful dream but could not remember when she woke up ? Case dream vanished prevalent and many are wondering why. Now scientists have found the answer to the big question mark .
Most people can easily remember dreams when you wake up and the other half could only remember it once in a while . Why is that ? A group of French researchers has found the answer while finding bagiamana brain mechanisms could save the dream .
The scientists divided the respondents into two groups of 41 . The first group are those who can easily recall his dream . They were given an average of 5.2 a dream in the morning , every week . The second group is those who can not remember the dream , a dream that is only given 2 each month .
The team led by Perrine Ruby , researchers at the Lyon Neuroscience Research Center that found there are areas in the brain responsible for remembering dreams and record it in memory when a person is sleeping .
In the human brain , there temporo - parietal junction , it is a central part of information processing in the brain . Based on the research showed that people easily remember the temporo - parietal dreams have more active . Increased activity in the region is believed to facilitate the process of memory storage in the dream .
They are easy to remember dreams are usually more frequent waking during sleep than those who can not remember the dream . Brain reminder of the dream is also more reactive to stimuli and noise when they sleep more easily maintained . Thus the results of the study outlined in the paper published in the journal Neuropsychopharmacology .
" This explains why they are easy to remember dreams are usually more reactive to environmental stimuli , more frequent waking during sleep , and better codify dreams into memories than those who can not remembering dreams , " Ruby said as quoted by the Daily Mail and written , Monday ( 03/3/2014 ) .
" Indeed , when the sleeping brain can not store new memory , the brain must be woken up to be able to do it , " he added .
Increased reactivity of the brain causing people easily awake at night . In that short period of waking , dream will be stored into memory . In contrast , the low activity in the temporo - parietal junction causing people rarely awake so that brain can not keep a dream .
The difference between the ones that are easy to remember dreams and people who are not only difficult to remember dreams occur during sleep . Scientists also found berbedaan when they are awake .
To see the difference , the researchers used positron emission tomography ( PET ) . The tool serves to measure the spontaneous brain activity of respondents when they are sleeping or awake .
They are easy to remember a dream show stronger brain activity in the area of ​​the medial prefrontal cortex ( mPFC ) and the temporo - parietal junction ( TPJ ) . Both of these areas of the brain known to be involved in the brain's reaction to stimulus from the outside .
