Document Summary

Eeg"s have proven the brain"s auditory cortex response to sound stimuli even during sleep. Our bodies roughly synchronize with the 24 hour cycle of day an night by an internal biological clock called the circadian rhythm. Age an experience can alter our circadian rhythm. About everything 90 minutes we cycle through four distinct sleep stages. Rem (rapid eye movement) is a recurring sleep stage during which vivid dreams commonly occur. Test was done on 8 year old armond aserinsky done by his father, a university of chicago grad student. The researcher can use an eeg to show the alpha waves of your awake but relaxed state. Alpha waves: the relatively slow brain waves of a relaxed, awake state. First stage is non-rem sleep stage 1 or nrem-1. The stage allows you to have fantastic images resembling hallucinations. Hallucinations: false sensory experiences such as sing something in the absence of an external visual stimulus.
