Power naps linked to improved information retrieval

23 Mar, 2015 | by Ion Gireada | 0 comments
Power naps, shorts bursts of sleep, have well documented health benefits. To the list of positive effects, improved memory emerges as an additional benefit, a new study found. Naps seem to lead to a five-fold improvement in memory functions, emphasizing information retrieval as key factor to learning success. Scientists highlighted…

As people age, they get forgetful of simple things such as where they last placed the key, of where have you put the papers in the office, but these should not be considered signs of Alzheimer’s disease. In a couple, the woman is the one more likely to see her…


“Artificial memories” created in sleeping mice

9 Mar, 2015 | by Daniel Tomas | 0 comments
Similar to abilities depicted in “Total Recall”, it is now possible to have artificial memories created during sleep, which then become “real” when the sleeper awakes, new research suggests. The process was successful in mice, but there is no indication it could be used in human subjects. The research team…


Memory forming locations identified with unmatched precision

28 Nov, 2014 | by Ion Gireada | 0 comments
Until recently, scientists had only an approximate understanding of where memories are formed. However, scientists determined with impressive accuracy the locations in the brain where humans generate their memories. Researchers from the University of Magdeburg and the German Center for Neurodegenerative Diseases (DZNE) collaborated in putting together a team of…


Brain interprets virtual and real worlds differently

26 Nov, 2014 | by Ion Gireada | 0 comments
Brain neurons have different reactions to virtual reality than they do real-life environment, new study shows. The finding has important significance to people using virtual reality in areas of gaming, military, commercial, scientific, or other areas. The study was published in the journal Nature Neuroscience. Mayank Mehta, professor of physics,…


Inflammation at brain level affects ability to retrieve memories

15 Sep, 2014 | by Ion Gireada | 0 comments
A team of neuroscientists concluded brain inflammation impairs the ability to retrieve memories of similar but distinct events. The study, published in The Journal of Neuroscience, and conducted at University of California by Jennifer Czerniawski and John Guzowski, identified the mechanism responsible for brain impairments affecting communication between neurons in…
