Spatial neglect.

Neglect, a failure to attend or act in one part of space, is a common disturbance following cerebral lesions. This article outlines the signs and symptoms of neglect. Recent attempts to disentangle sensory/attentional from motor/intentional aspects of neglect are outlined. Neglect in directions other than the horizontal is discussed, as are directional biases found in normal control subjects. The article also examines the anatomy of lesions causing neglect and theoretical models of the cerebral mechanisms underlying neglect.
