a. Example scan path from patient G.K. who has infarction of the right inferior parietal lobe but has sparing of the frontal lobe
[1]. The search task was to find letter Ts amongst distractor Ls. There is profound neglect of the left side of the array and many re-fixations on the right. Figure from Husain et al. [1] ‘Impaired spatial working memory across saccades contributes to abnormal search in parietal neglect’ Brain (2001), 124, 941–952, by permission of Oxford University Press. b. Visual targets successfully cancelled during a cancellation task involving random shapes by Weintraub and Mesulam [52]. This patient has a large right parieto-temporal lesion and dramatically neglects the left hemifield.

Visual targets successfully cancelled during a cancellation task involving randomly positioned letters by Weintraub and Mesulam [52]. This patient has a right superior frontal infarct and neglects the left hemifield.
