Scientists suggest a new ‘brain wave’ for sound sleep and improved memory
German researchers have found out in a recent study that by actually allowing a stream of mild electrical stimuli throughout the night in short jolts they can stimulate a person's mind helping him definitely to clearly recall the previous days events much more clearly than he would ordinarily be able to do.

Neuroscientist Lisa Marshall of the University of Lübeck and her colleagues in their study found that applying electrical stimuli to the brain scalp which is closely akin to brain's signal during deep sleep helped to improve 'recall' of word pairs memorized by volunteers the night before better than the control group who were given no electrical stimulation .

A stimulating deep sleep seems to augment the replay of recently imprinted memories in the brain thus enabling it to be consolidated and stored for a long term. The results of their study was published in an online medical journal,' Nature.'

This study offers an extremely simple method which can be practically implemented as it is sans sophistication and complex equipment and certainly offers much hope for treatment of behavioral disorders and memory loss related disorders linked to old age and sleeplessness .Researchers believe that it will be a massive breakthrough if by restoring significant deep stage of sleep ,memory loss can be limited for those who suffer from it.

Sleep that unravels the raveled sleeve of care as Shakespeare noted long ago seems to be the only way to beat a fevered brain. So to run down memory lane you need a shock and sound snooze!
