1. aphasia, conduction A type of fluent aphasia characterized by an impaired ability to repeat one and two word phrases, despite retained comprehension. This condition is associated with dominanthemisphere lesions involving the arcuate fasciculus (a white matter projection between Broca's and Wernicke's areas) and adjacent structures. Like patients with Wernickeaphasia (APHASIA, WERNICKE), patients with conductionaphasia are fluent but commit paraphasic errors during attempts at written and oral forms of communication.
