Brain region discovered that only processes spoken, not written words: Study of rare dementia shows selective attack on areas of brain

Even though these patients could hear and speak perfectly fine, a disease had crept into a portion of their brain that kept them from processing auditory words while still allowing them to process visual ones. Patients in the study had primary progressive aphasia (PPA), a rare type of dementia that destroys language and currently has no treatment.

The study, published March 21 in the journal Cognitive and Behavioral Neurology, allowed the scientists to identify a previously little-studied area in the left brain that seems specialized to process auditory words.

If a patient in the study saw the word "hippopotamus" written on a piece of paper, they could identify a hippopotamus in flashcards. But when that patient heard someone say "hippopotamus," they could not point to the picture of the animal.

    >They do in highly phonemic languages. It's why Rome's Latin and Greece's Greek speakers couldn't read without pointing their finger on the paper and slowly articulate the words.

    Well, I'm no expert but I saw Roman or early medieval lapides written
