The learning disability dyslexia is caused by a problem with signal processing involving speech recognition in the brain, according to a new study. Although they do not lack intelligence, people with dyslexia have trouble reading, understanding and explaining individual words or entire texts. Researchers in Germany found this is because a part of their brain's thalamus -- called the "medial geniculate body" -- does not process speech sounds correctly.
