Cancellation of visuoparietal lesion-induced spatial neglect.

In humans lesions of right visuoparietal cortex induce a neglect of the contralesional visual field that is characterized in its mild form by inattentiveness to objects and events and, in its more severe form, by a condition that has many features that are indistinguishable from blindness. Here we show that spatial neglect can be induced in cats by lesions of posterior and inferior visuoparietal cortex, and that the lesion-induced neglect can be cancelled by cooling deactivation of the same region in the opposite hemisphere.
