What TV does
to your head
Low Alpha Waves: Causes: Televison
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. A high frequency alpha waves [sic] does not occur normally when the eyes are open.
Watching television is neurologically analogous to staring at a blank wall.
Hypnosis also works through induction of slow brain wave states. Alpha waves are present during the 'light hypnotic' state used by hypno-therapists for suggestion therapy.
Low Alpha Waves: Causes: Radiant Light
Low Alpha Waves: Causes: Positive Ions
Synchronous Alpha brainwaves
Fm Theta Brainwaves 4-8 mHz
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.
Alpha Brainwaves add images and visuals; you could view this as escape from reality. Too much alpha activity leads to excessive escapes and too many daydreams.
Alpha ranges between 7-12 hertz and is prominent.
When Alpha wave activity becomes 'locked' and inhibited, active participation of vital brain areas cannot occur with efficiency.
Psychophysiologist Thomas Mulholland found that high frequency alpha waves [sic] does not occur normally when the eyes are open. In fact, Mulholland’s research implies that watching television is neurologically analogous to staring at a blank wall.
