Study Puts New Spin on 'Sound Sleep'
THURSDAY, April 11 (HealthDay News) -- Playing a certain type of sound stimulation during sleep might help improve your memory, a small new study suggests.
Slow oscillations in brain activity occur during slow-wave sleep and are critical for retaining memories. This study found that playing sounds synchronized to the rhythm of those oscillations enhances the oscillations and boosts memory.
The findings suggest an easy and noninvasive way to enhance memory, according to the authors of the study, which was published online April 11 in the journal Neuron.
"The beauty lies in the simplicity to apply auditory stimulation at low intensities -- an approach that is both practical and ethical, if compared, for example, with electrical stimulation -- and therefore portrays a straightforward tool for clinical settings to enhance sleep rhythms," Dr. Jan Born, of the University of Tubingen, in Germany, said in a journal news release.Read entire article...
