Ok..keratan artikel menarik tentang kesan TV keatas otak yang mungkin korang belum tahu.
"When you watch TV, brain activity switches from the left to the right hemisphere. In fact, experiments conducted by researcher Herbert Krugman showed that while viewers are watching television, the right hemisphere is twice as active as the left, a neurological anomaly. The crossover from left to right releases a surge of the body’s natural opiates: endorphins, which include beta-endorphins and enkephalins. Endorphins are structurally identical to opium and its derivatives (morphine, codeine, heroin, etc.). Activities that release endorphins (also called opioid peptides) are usually habit-forming (we rarely call them addictive). These include cracking knuckles, strenuous exercise, and orgasm. External opiates act on the same receptor sites (opioid receptors) as endorphins, so there is little difference between the two."
"Psychophysiologist Thomas Mulholland found that after just 30 seconds of watching television the brain begins to produce alpha waves, which indicates torpid (almost comatose) rates of activity. Alpha brain waves are associated with unfocused, overly receptive states of consciousness. A high frequency alpha waves 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.
I should note that the goal of hypnotists is to induce slow brain wave states. Alpha waves are present during the “light hypnotic” state used by hypno-therapists for suggestion therapy."
