Losing Sensory Perception
Joseph Chilton Pearce

Out of Germany come the studies that show how increased environmental stimulation causes the brain to close, to narrow its perception filters at a rate of approximately 1% per years. Over a ten year period the brain will register 10% less nuance of color, sound, taste, etc., thus requiring media producers to increase the pace, volume, explosive violence, the overall level of stimulation, which in turn, causes the brain to further limit and constrict actual sensory perception and sensitivity. The brains of our grandparents literally perceive a vastly different spectrum of sensations than today’s developing brain.
