Doctors prescribe Ritalin to hyperactive kids to calm them down and increase their attention span. And college kids have taken to using Ritalin to concentrate when they hit the books. But it hasn’t been clear how the drug boosts focus. Now a paper in the journal Biological Psychiatry suggests how it might work.
But at high doses, the prefrontal cortex tuned out, and Ritalin’s effects were similar to those of other stimulants. The rats lost their cognitive edge and they became hyperactive, sniffing and licking repetitively. So Ritalin shows you can indeed have too much of a good thing—to the point of distraction.
