sleep. When electrodes are attached to the face and scalp of sleepers‚ different patterns are produced on the graphic record called the electroencephalogram or EEG. The patterns vary in frequency and amplitude of the waves shown on the EEG. These waves reflect patterns of brain activity. It was discovered that the patterns on the EEG change throughout the night to correspond to various stages of sleep. Wakefulness is characterized by beta waves and relaxation is characterized by

Sweden-based Nordic Society for Invention and Discovery (NSID)‚ the No More Woof is a lightweight headset‚ sized for dogs‚ with sensors that can record electroencephalogram (EEG) readings. The EEG readings are then analyzed by a Raspberry Pi microcomputer‚ which will‚ according to NSID‚ be programmed to translate those EEG readings into simple phrases like‚ "I’m hungry‚" or "Who is that person?" Once translated‚ those phrases will be reported over a small speaker. Paging Dr. Doolittle If

Stages of Sleep The EEG (Electroencephalogram)of a waking person is clearly different than that of a sleeping person. The difference in EEG patterns that occur during sleep has made it possible to divide sleep into five different stages. Stage One We experience stage one of sleep when we are half asleep and half awake; our eyelids feel heavy‚ we feel groggy and suddenly without notice we fall asleep. Stage one counts for more or less 5% our total sleep during the night. Stage

The original qualitative model was elaborated to quantitative versions that included the ultradian dynamics of sleep in relation to the non rem-rem sleep cycle.

Title: The Evolution of serial Killers Introduction: For centuries Stories about Serial killers have graced the covers of newspapers and magazines. Famous stories like “Jack The Ripper” and Edward “Ed” Gein‚ which influenced many popular films such as Psycho and The Silence of the Lambs. There are so many questions surrounding this topic one being: Nature versus Nurture? Is this need to kill a simply male completion in an effort to show status and be “The Alpha Male”?
