"By comparing how neurons act when the brain is in different states — such as when a subject has taken a drug versus when they haven’t — researchers can create more complete and useful models of how brain cells and behavior are linked."

this reads like it was written for toddlers. "Did you know that sometimes we test drugs in things called experiments?" Wow that's incredible.

also the study doesn't explain how ritalin "works" (is "attention" something that can be dull? or sharp?). it says

"We discovered that orally administered methylphenidate... increases spatially selective visual attention"

how you go from that to "Research helps explain how Ritalin sharpens attention". come on guys
