You don't seem to understand. The whole idea of electrical signals
in the range 0.5 to 20 Hz recorded from the surface of the brain (or
the scalp) is call "electroencephalogram". The alpha, beta, delta,
and theta bands are subdivisions within this spectrum: The delta
waves are generally 0 to 4 Hz, the theta are 4 to 7 Hz, the alpha
are 8 to 13 Hz and the beta are 13 to 40 Hz (more or less).
If you search for "electroencephalogram alpha" or "EEG delta"
you will get references for what you want. But again, don't search
newsgroups. Either search the "internet" using google (or whatever
search strategy you like) or search the scientific literature using
Pubmed (or whatever search strategy you like).
