| When
there is a lesion in one of the parietal lobes, patients may have
a subtle neglect of the opposite side. For example, if there
is a lesion in the right parietal lobe, and the patient is asked to
close the eyes, and both hands are touched, he may not feel the left
hand being touched. This is known as "extinguishing to
double simultaneous stimulation" and is quite sensitive at picking
up subtle structural lesions in the parietal lobes. |
