[Auditory comprehension in XXXX due to a medial lesions of the @entity75 ].

@entity1 @entity12862 @entity75 @entity1650 @entity5785 @entity1188
We assessed the anatomical findings and auditory comprehension of six @entity1 with @entity5785 due to medical lesions of the @entity75 . All @entity1 were right-handed and were initially mute for several hours after the onset, and they exhibited mild paresis of the right lower extremity. Their spontaneous speech was sparse and not fluent, and sometimes accompanied by @entity12862 , but their articulation was normal and repetition was excellent. They had difficulty in recalling words. A diagnosis of @entity5785 was made on the basis of their clinical symptoms. All @entity1 were found to have an @entity1188 in the left medial frontal region by MRI and/or CT. We administered the Western Aphasia Battery and 50 line drawing pointing task in order to evaluate auditory comprehension. Based on the results we concluded that there is no @entity1650 of single words when lesions are limited to the superior frontal gyrus, but that lesions extending to the middle frontal gyrus interfere with auditory comprehension of single words. Our observations indicate that the middle frontal gyrus plays an important role in auditory comprehension of single words. All of the @entity1 displayed @entity1650 of sentences even when their lesions were strictly limited to the medial frontal lobe. This suggests that the medial frontal lobe plays some role in the auditory comprehension of sentences.
