    I've heard of people having to take similar tests for sleep apnea.

    As sleep progresses and becomes deeper and deeper, the EEG recordings reveal brain waves which are slower in frequency and higher in amplitude. Stages three and four of sleep reveal these slow waves which are called delta waves.(3-5 cycles per second). (Try to remember delta = deep sleep.)

    When in a deep sleep the brain waves would be slower in frequency and higher in amplitude as the brain as shut down not completely... In to deep daze ie (sleep) it makes sense

    Electromyograph(EMG) is a device that measures electrical activity in the muscles. Electro-ocular gram (EOG) is used to study eye movements.

    As one would suppose brain activity slows when one is sleeping, the deeper the sleep, the change in brain waves from Alpha to Delta.

    I guess this study is conclusive to adults and humans, I have identified the rapid eye movement in children and pets as they sleep.

    I think someone would have to be a good sleeper to be able to sleep in a sleep laboratory
