Better turn those lights up! via Prevent Disease: Spending too much time in dimly lit rooms and offices may actually change the brain's structure and hurt one's ability to remember and learn, indicates groundbreaking research by Michigan State University neuroscientists. All life evolved with the electromagnetic frequencies from the sun and the earth, and these frequencies are considered essential to all life. Life itself synchronizes and harmonizes with these frequencies. But what happens when these frequencies are disrupted by modern technology? The researchers studied the brains of Nile grass rats (which, like humans, are diurnal and sleep at night) after exposing them to dim and bright light for four weeks. The rodents exposed to dim light lost about 30 percent of capacity in the hippocampus, a critical brain region for learning and memory, and performed poorly on a spatial task they had trained on previously. The rats exposed to bright light, on the other hand, showed significant
