Never had a lively dream that felt so true, it was strange and you forget the moment you wake up? For years, science has tried to accurately locate how and why our brains retain some knowledge and TOSS dreams of rest, including.Many scientists Believe that our brain emerges unnecessary information to the makeup room for the new one. Others argue that we keep mentally forgotten flexible, encouraging creativity and imagination. There was evenstudies Finding who disengage unnecessary memories reduces the risk of Alzheimer's disease.

However, recently, a group of scientists stumbled more deeply into the science of memory, while studying sleep regulation in mice. In their new document, published Thursday in the magazineScience, Japanese and American researchers say thatDuring rapid eye movement (REM) deep sleep stage, the brain is actively forgetting. In addition to explaining why dreams are often forgotten during paradoxical sleep, it also suggests that neurons found in the brain could be controlled in general.

"You are wondering why we forget a lot of our dreams? Was the question asked by Thomas Kilduff, Ph.D., Director of the Neuroscience Center in Sri International, Menlo Park, California, and the main author of the study. "Our results suggest that the firing of a particular group of neurons during paradoxical sleep checks if the brain remembers new information after sleep a good night. »

While looking Orexin, a hormone to the study of obesity and narcolepsy, the researchers noticed that melanin concentration of hormones, (SMI) molecule neurons associated with both sleep and appetite were activated the More often (52.8 percent) when the mice were at the way to go to sleep. While the mice were awake, they only 35 percent and 12 percent have shot each time.

They also have indices that these maternal and child health cells could play a role in memory and learning. "Previous studies carried out in other laboratories, we already knew that MCH cells were active during paradoxical sleep," Dr. Kilduff continued. "After discovering this new circuit, we thought these cells could help brain store memories. »

When testing researchers turned NEURONES MCH and turned off. They were surprised to note that "turn on" the cells during retention worse, while deactivating them actually improved memories. Thanks to more tests they determined that the MCH neurons played exclusively this role during paradoxical sleep.

"These results suggest that the MCH neurons help the brain fork actively new, perhaps, unimportant information," Dr. Kilduff said. "Since dreams are considered to occur mainly during paradoxical sleep, the sleep phase when maternal and infantive health cells light up, the activation of these cells can prevent the contents of a dream from being stored in the hippocampus , therefore, the dream is quickly forgotten. »

Although our selective forms of brain is interesting in oneself that the reason why the potential we forget about our dreams-researchers hope that by solidifying the relationship between the neurons MCH and forget, research in neuroscience will be able to go from 'before. Janet He, Ph.D., Director of the Program in Ninds, stresses that this could be extremely useful in terms of memory-related diseases, including post-traumatic stress syndrome and Alzheimer's disease.

"This study provides the most direct evidence that paradoxical sleep can play a role in the way the brain decides who memorizations of," she says.

Some experts are not too excited about these new discoveries, affirming the study has major defects, especially when it comes to its potential implications with Alzheimer's disease. "The study makes titular hypotheses such as what constitutes unnecessary memory for a mouse? »Carolyn Dean, MD, ND, author ofAlzheimer's book Alland founder of the RNA Renew Eat this, not that! Health. It also emphasizes that researchers do not take into account the nutritional nutrition and nutritional status, significant variables that should not be neglected "as the functioning of the organization work in synergy and not independent of other systems. »

"Certainly, food and nutrition, as well as environmental factors and toxic heavy metals have been involved as a pineal calcification in the pathology of Alzheimer's disease," Dr. Dean maintains, emphasizing magnesium like L 'one of them. Preliminary and contradictory information may indicate the lack of cause. However, "this information may be a random factor in the pathology, but not a root cause it tends to act as a distraction or adds to confusion.
