Watching too much television can actually cause harmful changes to a child's brain structure, according to a study conducted by researchers from Tohoku University in Japan and published in the journal Cerebral Cortex. The more television watched, the more severe the changes.
"TV viewing is directly or indirectly associated with the neurocognitive development of children," the researchers wrote. "At least some of the observed associations are not beneficial and guardians of children should consider these effects when children view TV for long periods of time."
The researchers conducted magnetic resonance imaging (MRI) scans on the brains of 276 children between the ages of five and 18, evenly split between girls and boys. The children and their caregivers provided detailed information about how much time each child spent watching television per day. The amount of television viewed varied between zero and four hours per day, averaging about two.

Meanwhile, a separate study, conducted recently by researchers from Emory University, found that college students who read the novel Pompeii by Robert Harris showed increased conductivity in regions of the brain associated with language receptivity. These neurological changes began on the first day of reading and lasted for five days after completion of the book.
"It remains an open question how long these neural changes might last," researcher Gregory Berns said. "But the fact that we're detecting them over a few days for a randomly assigned novel suggests that your favorite novels could certainly have a bigger and longer-lasting effect on the biology of your brain."
