Spatial neglect is often perceived as a "heterogeneous collection of symptoms"
with controversial anatomical correlates. However, a clear framework for core and
satellite symptoms exists. Here we review the literature when viewed from the
perspective of these different syndromes, and find clear pattern of anatomical
injury. Specifically, the combined symptoms of biased gaze direction and search -
with no awareness of these symptoms-is seen following structural damage to
(particularly right hemisphere) perisylvian regions. Object centered deficits
such as biased line bisection are due to more posterior (and possibly inferior)
injury. Finally, extinction is associated with damage to the temporo-parietal
junction. Further, we describe key choices that must be made to parse the spatial
and attentional syndromes that result from right hemisphere injury, including the
investigation of both acute and chronic injury as well as the use of functional
and structural modalities.
