Sound Stimulation During Sleep Can Enhance Memory

How long before your doctor prescribes this in the hospital post-stroke to improve your memory? 25-30 years? Ask for it. Its the only way this will get there faster than 25 years. Don't self prescribe, you know how dangerous it is to listen to music.

Slow oscillations in brain activity, which occur during so-called slow-wave sleep, are critical for retaining memories. Researchers reporting online April 11 in the Cell Press journal Neuron have found that playing sounds synchronized to the rhythm of the slow brain oscillations of people who are sleeping enhances these oscillations and boosts their memory. This demonstrates an easy and noninvasive way to influence human brain activity to improve sleep and enhance memory.
Dr. Born and his colleagues conducted their tests on 11 individuals on different nights, during which they were exposed to sound stimulations or to sham stimulations. When the volunteers were exposed to stimulating sounds that were in sync with the brain's slow oscillation rhythm, they were better able to remember word associations they had learned the evening before. Stimulation out of phase with the brain's slow oscillation rhythm was ineffective.
