    excuse me,I need to know some questions:
    1)what human brain wave is?
    2)how does the human brain wave work?
    3)how long the brain wave is?
    4)whether the brain wave same as the magneton exist in nature?

    If you know the answer please send to me as quick as possible!

    Thank you!

    It's a popular term that has many different meanings. Some people mean the
    rythms in EEG when they say brain wave, others mean something
    transcendental.


    > 2)how does the human brain wave work?


    Depends on what you mean. If you mean the EEG things, it's a weighed average
    of firing patterns that occur in the cerebral cortex, only the outher layers
    (say up to 5 or 6 neurons), showing cerebral activity.

    > 3)how long the brain wave is?


    Depends on the wave. Brain activity never ceases, unless you die. Individual
    waves are often classified according to frequencies (like alpha, beta,
    theta, etc) or wave lengths (e.g. P400 is a positive going potential of 400
    miliseconds length).


    > 4)whether the brain wave same as the magneton exist in nature?


    I don't understand thequestion, but magnetrons have much higher frequencies
    than any interesting part of the EEG.

    Questions in a newsgroup are answered in that group.
