According to the new findings, it is being suggested that research in brain rhythms during sleep could lead to improvement in sleep treatments.

A team at Massachusetts General Hospital have found brain rhythm during sleep as an essential emblem of wakefulness during sleep. These brain rhythms have become a factor for people to wake up by noise or any other disturbances.

To make this research successful, the researchers have used EEG of 13 members who slept for three nights in the MGH lab. The members were exposed to various sound disturbances for 10 seconds. The sound intensity was increased after repeated intervals. This procedure was continued until the EEG recorded a disruption in sleep.

The EEG analysis showed that the intensity of the alpha signal showed that the members could get disturbances in their sleep. This whole analysis predicted that a stringer alpha signal could make sleep more fragile.

"We found that the alpha rhythm is not just a marker of the transition between sleep and wakefulness but carries rich information about sleep stability", said study author Scott McKinney, informatics manager at the MGH Sleep LAB, during a hospital release.

This study was published in PLoS One journal.
