Hi Masato!
Wernicke’s area is located in the temporal lobe. The parietal lobe plays some role in auditory processing and comprehension, so some degree of aphasia may be present with a left parietal lobe stroke – though this is less clean than a frontal or temporal lobe infarct.
Homonymous hemianopsia could occur with damage to the occipital lobe, inferior temporal lobe, or deep structures like the thalamus and internal capsule.
An internal capsule stroke would be most likely to present with pure motor and sensory deficits. The patient could have dysarthria affecting speech but aphasia would not be present.
Hope this helps!
