By studying stroke victims who have lost the ability to spell, researchers have pinpointed the parts of the brain that control how we write words.

In the latest issue of the journal Brain, Johns Hopkins University neuroscientists link basic spelling difficulties for the first time with damage to seemingly unrelated regions of the , shedding new light on the mechanics of language and .
