Uninterrupted deep sleep was crucial to this progress. Nathan Whitmore, a PhD candidate in the Interdepartmental Neuroscience Program at Northwestern said, “It’s a new and exciting finding about sleep, because it tells us that the way information is reactivated during sleep to improve memory storage is linked with high-quality sleep .” Memory reactivation did not benefit and may even be harmful to study participants with EEG data (a recording of electrical activity in the brain picked up by electrodes on the scalp) that indicated interrupted sleep. The reactivation resulted in a relative improvement of a little over 1.5 more names recalled in those who slept uninterrupted throughout the specif

Its official, a good night sleep is not just an important element in your beauty regime, it is also essential to keep you active and alert. A study at the Brigham and Women’s Hospital indicated that lack of sleep not only leads to lethargy , but also affects complex visual search tasks adversely! Activities like power plant monitoring, air-traffic control and baggage screening, which are safety-sensitive, are often affected by lack of sleep. These activities demand a process of repeated retrieval of visual information and quick memory encoding along with a good amount of decision making related to the acquired information. In this study, 12 participants were scheduled to sleep for about 10 hours every night in the beginning and then for about 5 hours, with sleep times in a 28-hour cycle, similar to someone suffering of acute jet lag . It was thus recorded that the time taken by the participants to perform visual search computer tasks was more when there was a lack of sleep.
