This assumption seems unlikely due to the following reasons.

None of the 22 patients in our study² had a lesion of the parietal lobe according to the classification based on the computed tomographic or magnetic resonance imaging scans.^{2(p 479)} Although neglect may occur after lesions in several brain areas outside the "classical" parietal region, persistent neglect is extremely rare in patients with occipital or temporal lesions.³ Moreover, persistent neglect occurs almost exclusively after right hemisphere lesions.
