DELTA brainwaves are in the 0.5 to 4 cycles per second range. This pattern is normally associated with very deep sleep and very deep meditation.
THETA brainwaves are in the range of 4 to 7 cycles per second. This pattern is associated with light sleep and deep rest.
ALPHA brainwaves are in the range of 7 to 12 cycles per second. This is a pattern which prevents concentration.
BETA brainwaves range from 13 to 27 cycles per second. These patterns allow us to analyze things and situations. Associated with alert mental activity.
GAMMA brainwaves operate above 27 cycles per second. Associated with hyperactivity or quick sudden bursts of physical activity.
While watching television, the brain appears to slow to a halt, registering low alpha wave readings on the EEG. This is caused by the radiant light produced by cathode ray technology [CRT, LCDs also?] within the television set [increases serotonin levels?]. Even if you're reading text on a television screen the brain registers low levels of activity. Once again, regardless of the content being presented, television essentially turns off your nervous system....
Psychophysiologist Thomas Mulholland found that after just 30 seconds of watching television the brain begins to produce alpha waves, which indicates torpid (almost comatose) [slow] rates of activity. Alpha brain waves are associated with unfocused, overly receptive states of consciousness....
...In this case they were shocked by the strange appearance, sudden materialization and loud voice of the Hare Krishna devotee. In other words, the people went into an alpha state for security because they didn't want to confront the reality before them. In alpha, they were highly suggestible so they responded to the suggestion of taking the book; the moment they took the book, they felt guilty and responded to the second suggestion: give money.... While watching this hustler, I was close enough to notice that many of the people he stopped exhibited an outward sign of alpha--their eyes were actually dilated....
...My attorney obtained copies of the patents which I gave to some talented Hollywood sound engineers, asking them to create a new technique. They found a way to psycho-acoustically modify and synthesize the suggestions so that they are projected in the same chord and frequency as the music, thus giving them the effect of being part of the music. But we found that in using this technique, there is no way to reduce various frequencies to detect the subliminals. In other words, although the suggestions are being heard by the subconscious mind, they cannot be monitored with even the most sophisticated equipment. If we were able to come up with this technique as easily as we did, I can only imagine how sophisticated the technology has become, with unlimited government or advertising funding. And I shudder to think about the propaganda and commercial manipulation that we are exposed to on a daily basis....
