Acoustic Stimulation, Sleep, and Memory

May 18, 2017

Patients underwent one night of a sham stimulation followed by pink noise stimulation delivered during slow wave activity.

Research published in Frontiers in Neuroscience from Northwestern University found that syncing pink noise to EEG recordings might have positive outcomes. Pink noise is defined as a soothing sound with each octave possessing equal energy

Patients underwent one night of a sham stimulation followed by pink noise stimulation delivered during slow wave activity. Verbal paired-associate memory was tested before and after sleep.

Researchers found that slow wave activity was enhanced on EEG and sleep-dependent memory storage was improved.
