Abstract
Article abstract-We describe a patient who had sequential strokes in both hemispheres with a severe unilateral spatial neglect after a first right-sided parietal infarct and abrupt disappearance of the neglect after a second left-sided frontal infarct. The first lesion involved the caudalmost right angular gyrus (area 39), whereas the second lesion involved the left frontal eye field (area 8) and surrounding cortex. Those two cortical areas are assumed to have a pivotal role in modulating both shifts of attention within extrapersonal space and saccadic eye movements through their connections with subcortical structures, in particular, superior colliculi and thalamic nuclei. Our case supports the existence of a distributed anatomic-functional network in subserving directed spatial attention.
