A Parietofrontal Network for Spatial Awareness in the Right Hemisphere of the Human Brain

INTRODUCTION

Patients with lesions of the right hemisphere often show signs of left-sided unilateral neglect. Left-sided neglect may impair the ability of patients to live independently and entails a poor functional outcome. When exploring a visual scene, patients with left-sided neglect fail to pay attention to left-sided objects. They do not eat from the left part of their dish, they bump their wheelchair into obstacles situated on their left, and they have a tendency to look to right-sided details as soon as a visual scene unfolds, as if their attention were "magnetically" attracted by these details.1 On visuospatial testing, they fail to cancel or describe left-sided targets in search tasks, deviate rightward when bisecting horizontal lines, and fail to copy the left part of drawings1-2 (Figure 1).
