The Sciences, May 2010, No 501 - The activity of the brain at rest

The brain regions that show a high level of activity when our mind wanders aimlessly may be essential to understand some neurological diseases, and perhaps even consciousness. Marcus E. Raichle

neuroscience have long believed that, when our mind is idle, the circuits of the brain were switched off. Experiments based on neuroimaging have instead shown the presence of a persistent level of background activity. This so-called "default mode" could be essential in planning future operations. Faulty circuits in the brain areas involved in this mode could cause disease, dall'Alzheimer to schizophrenia.

The dual function of dreams - The Science of April 23, 2010

The recent experience would be processed simultaneously in the hippocampus according to the current problems, and higher cortical areas to test the applicability of the new information compiti più complessi e astratti
I sogni sarebbero il modo in cui il cervello ci permette di sentire la complessità del lavoro di consolidamento nella memoria delle esperienze recenti in modo, sul breve termine, da migliorare le capacità di svolgere con efficienza specifici compiti e, sul lungo termine, di trasformare l'informazione in esse contenute per integrarle nel nostro repertorio di comportamenti e farne uno strumento che possa trovare un più ampio spettro di applicazione.

E' questa la conclusione a cui sono pervenuti ricercatori del Beth Israel Deaconess Medical Center sulla scorta dei risultati di una ricerca ora pubblicata sulla rivista Current Biology.

"Ciò che ci ha realmente eccitato è che dopo hundred years of debate on the function of dreams, this study tells us that they are the way the brain to develop, integrate and really understand the new information, "says Robert Stickgold, who led the research." Dreams are a clear indication that the sleeping brain is working on the statements on various levels, including the ways that will improve performance. "

In particular the analysis of data collected during a series of experiments to evaluate the influence of sleep on learning abilities, the researchers noted that the sleeping brain appears to play two distinct functions: while the hippocampus processes information that is readily understandable, higher cortical areas simultaneously attempt to apply the new information to the tasks of a more complex and less tangible.

"Our brains, on a non-conscious, working on things that it considers particularly important. Every day we are faced with a tremendous amount of information and new experiences. It seems that our dreams put the question: How can I use this information to shape my life? " (Gg)
