Wernicke, and later Geschwind, posited that the critical lesion in conduction aphasia is in the dominant hemisphere's arcuate fasciculus. This white matter pathway was thought to connect the anterior language production areas with the posterior language areas that contain auditory memories of words (a phonological lexicon). Alternatively, conduction aphasia might be induced by cortical dysfunction, which impairs the phonological output lexicon. We observed an epileptic patient who, during… 
The role of the arcuate fasciculus in conduction aphasia.
TLDR
Clinical and neurophysiological findings may suggest that the AF is not required for repetition although could have a subsidiary role in it.
Conduction aphasia as a function of the dominant posterior perisylvian cortex. Report of two cases.
TLDR
The authors report two cases that demonstrate that conduction aphasia is cortically mediated and can be inadequately assessed if not specifically evaluated during brain mapping, and a localization of language repetition to the posterior perisylvian cortex.
Phonological agraphia after superior temporal gyrus infarction.
TLDR
This patient showed a selective impairment of phonological agraphia in association with a focal infarction restricted to the left posterior superior temporal gyrus, suggesting that this region of the brain is an important node within a wider network of areas that subserve the phonological route for writing.

TLDR
It is concluded that conduction aphasia remains a controversial topic not only from the theoretic point of view, but also from the understanding of its neurologic foundations.

TLDR
Three patients with conduction aphasia are described; in addition to the distinctive language disorder, two of them had severe ideomotor apraxia while the other was entirely free ofApraxia, and a review of the literature would propose the following.
Conduction aphasia and arcuate fasciculus
TLDR
Three patients are presented who developed conduction aphasia after a small infarction almost exclusively confined to the arcuate fasciculus, which shows a rapid amelioration within a week after the stroke.

TLDR
Brain activation was assessed in the temporal, parietal and frontal multi-modal association areas that constitute parts of a large network that represent the specific anatomic substrate of the lexico-semantic processing of language.
