　　There's new evidence that too much screen time early in life can change the circuits (回路) in a growing brain. Scientists disagree, though, about whether those changes are helpful, or just cause problems.

　　The debate centered on a study of young mice exposed to a video game. "The mice showed big changes everywhere in the brain，" said researcher Ramirez. On the positive side, it meant that these mice were able to stay calm in an environment that would have stressed out a normal mouse. But it also meant they acted like they had a lack of attention, showed signs of learning problems, and were likely to do dangerous behavior. Generally, the results add to the evidence that parents should be very cautious about screen time for young children, Ramirez said.

　　A more positive explanation came from Professor Leah Krubitzer."The benefits may be more important than the negative sides，" Krubitzer said, adding that a less sensitive brain might succeed in a world where overstimulation (过度刺激) is a common problem.

　　It's true that this sort of stimulation may make a child's brain less sensitive in some ways. But it also may prepare the brain for an increasingly fast­paced world. "Less than 300 years ago we had an industrial revolution and today we're using mobile phones and we interact (互动) on a regular basis with machines，" Krubitzer said. "So the brain must have changed."

Krubitzer rejected the idea that the best solution is to turn_back_ the_clock. "You are likely to think of the good old days when you were a kid, and say, 'I didn't do that and I didn't have TV and look how great I turned out，'" Krubitzer
