Sleep Shortage Contributes To The Preservation Of Negative Experience


Experiments with volunteers have shown that partial sleep deprivation can even be worse than its complete absence: after the night "Non-Saute" it turns out it is more difficult to forget negative experience and easier to develop anxiety.Sleep Shortage Contributes To The Preservation Of Negative Experience

Sleep time – the key to work mechanisms of memory, and its lack is often associated with violations of normal training and memories. Anne Germain’s team from Pittsburgh University found that people sleeping twice as smaller decreases the ability to forget negative experience.

The Authors Note That Such A Sleep Mode Is Often Found Among Medical Workers and Military and Can Lead To The Development Of Anxiety and Post-Traumatic Disorders. Article of Scientists Has Been Published in The Magazine Biological Psychiatry: Cognitive Neuroscience and NeuroImaging.

Jermaine and Her Colleagues Conducted Experiments WITH 150 Healthy Volunteers. During The Night In The Laboratory, A Third of Them Slept Normally, A Third – Only Half of the Last Time, and A Third Did Not Sleep AT All. The Next Morning Everyone Passed The Procedure for Developed Cards of Three Colors, The Choice of Two of Which Led to A Weak, But Unpleasant Shock.

Next, For One of These Two Colors, An Inverse Procedure Was Made Designed to Convince The Brain That Now He is "Safe". Finally, In The Evening, Scientists Registered Volunteer Reactions for All Three Colors. In Parellel WITH THE ACTIVITY OF THE WORK OF THE BRAIN INVOLVED IN THE WORK OF EMOTIONS AND THE DEVELOPMENT OF FEAR REACTIONS.

"We Found That In A Group That Received Only Half of The Right Sleep Time, The Greatest Activity of The Regions Associated with Fear, And The Smallest – Those Involved In The Control of Emotions," Says Ann Jermain. IN FACT, EVEN THOSE WHO DID NOT SLEEP AT NIGHT AT ALL, THESE EFFECTS WERE NOT SO NODICEABLE. Their Brain Showed Less Activity WHILE THE REACTION OF FEAR.

The Authors Suggest That This Is Due To the Lack of A "Fast" Sleep Phase in Those Who Slept Half the Right Time. It Is In These Periods That Compete After The Long "Slow" Phase, The Memory Consolidation Occurs – The Streamlining Of New Experience, The Preservation of Imtem Links and The Removal of Unnecessary. SOLD OFF IN A SHORT TIME WITHOUT LONG-TERM CONSEQUENES FOR COGNITIVE FUNCTIONS, PERHAPS THE CARRIERS OF CERTIN RARE MUTATIONS ARE CAPABLE OF.
