However, the contralesional hemispace can \nbe determined by different frames of spatial coordinates, \nsuch as eyes-, head-, body-, or environment-centered coordinates. \nWe observed 2 patients with a right hemisphere stroke whose \nleft spatial neglect was modulated by distinct coordinates \nsystems depending on the task. Four tasks were given in \ndifferent conditions of central gaze and either the eyes \nor the head rotated 30\u00b0 to the right or 30\u00b0 to \nthe left. While the 2 patients had a retinotopic defect \nin 1 visual field quadrant that remained the same irrespective \nof gaze direction (upper or lower quadrant in 1 case each), \nthe other quadranopic field defect improved with eyes rotation \nto the right but not with head rotation, suggesting a head-centered \nspatiotopic deficit. Performance on line bisection was \ninfluenced both by eyes and head rotation, as well as by \nthe position of the lines with respect to the trunk midline, \nsuggesting the involvement of both head-centered and body-centered \ncoordinates. Visual imagery and auditory extinction were \nnot modified by changing the eyes or head position. These \nfindings suggest that distinct spatial coordinates are \nbrought into play depending on the tasks demands.
