Treatment was followed by a gradual but significant improvement in auditory comprehension (including single-word comprehension).
and further supports the role of the ventral system in auditory comprehension.
A ventral stream connects temporal and prefrontal regions via the extreme capsule and mediates meaning, e.g. in auditory comprehension.
To summarize, in Hebrew MH exhibited non-fluent speech with anomia and disturbances in auditory comprehension, but without difficulty in repetition.
Furthermore, he exhibited only limited disturbances in auditory comprehension in Arabic (t(3) = 5.7, p < 0.01), but significantly more disturbances in Hebrew.
We calculated the average percent error in auditory comprehension and naming tasks as a function of infarct volume using a non-parametric regression method.
Anatomical evidence, discussed by Scott and Johnsrude (2003), suggests that the pathways involved in auditory comprehension may run from both rostral and caudal parabelt auditory cortices anteriorly towards STS, but also to more posteriorly to the inferior temporal areas.
Our results regarding the N1 and N2 waveforms – particularly the significant correlations of N1 amplitudes with clinical language comprehension assessment results – suggest that these waveforms deserve further attention in the exploration of auditory comprehension impairment in aphasia.
We found that infarct volume was the only predictive variable in the production of semantic errors in both auditory comprehension and object naming tasks.
The second task was an oral naming task in which the patients were presented with 20 objects (not included in the auditory comprehension task) and were asked to provide their names (the Western Aphasia Battery object naming subtest).
A statistical correlation between N1 amplitude and measures for the severity of auditory comprehension measurement in aphasia has not been reported earlier, but in two studies that also dichotomized the aphasic patient groups in relation to auditory comprehension function, a larger N1 reduction in the severe aphasia groups has been reported [ 36, 43].
