repeat words or sentences.

slightly different patterns of activation may be seen among speakers of two or more languages.

The angular gyrus links the

visual region and Wernicke's area.

A patient who produces seemingly fluent but largely unintelligible speech and has poor comprehension of verbal material is most likely suffering from _______ aphasia.
