Amelioration of right spatial neglect after visuo-motor adaptation to leftward-shifting prisms.

Visuo-motor adaptation to rightward prismatic shifts reduces signs of left spatial neglect on a wide range of measures(Rossetti et al., 1998; Tilikete et al., 2001; McIntosh et al., 2002; Pisella et al., 2002; Berberovic et al., 2004). As there are hemispheric asymmetries in spatial attention mechanisms, it maybe useful to examine whether prism adaptation can produce similar improvements in neglect of the right hemispace following left hemisphere damage. We report improvement ina patient with mild right spatial neglect following adaptation to leftward-shifting prisms.
