Delta Wave

A delta wave is a high amplitude brain wave with a frequency of oscillation between 0–4 hertz. Delta waves, like other brain waves, are recorded with an electroencephalogram (EEG) and are usually associated with the deepest stages of sleep (3 and 4 NREM), also known as slow-wave sleep (SWS), and aid in characterizing the depth of sleep.

Famous quotes containing the word wave:

    “Through this broad street, restless ever,
    Ebbs and flows a human tide,
    Wave on wave a living river;
    Wealth and fashion side by side;
    Toiler, idler, slave and master, in the same quick current glide.”
    —John Greenleaf Whittier (1807–1892)
