Frontal versus Temporal Lobes and Languages

MRI studies have shown that distinct regions of the brain are used to process different types of sentences in different languages. For examples, sentences in which word order determined the relationships between the sentence elements (e.g., English language with sentences such as "Sally greets Bob") utilized parts of the frontal cortex that give humans the ability to put information into sequences. On the other hand, sentences in which inflection was providing that same type of information (e.g., Spanish language) utilized parts of the temporal lobe that specialize in dividing information into its constituent parts. The hope is that this information could prove valuable assistance in assessing how best to teach language to a person with brain damage in certain areas but not others, such as a person who has experienced a stroke.
