Hemi neglect (lose space on one side) vs hemi anopia (blindness in the visual cortex) a primary sensory deficit. Mostly common with right hemisphere damage leading to neglect of the left side of space. Hemi-anopia patients know this space is gone, try to compensate. Spatial neglect patterns of damage tend to overlap more closely with the ventral attention network. Sprague effect: lesion removed from a cat(cid:859)s right (cid:448)isual (cid:272)orte(cid:454) contralateral if you lesion the left superior colliculus, this compensates the lesion on the right (this evens it out by eliminating some competition on the other side of the brain) Prism adaptation therapy puts prism goggles on the patient uses the good side of the brain to compensate from the bad side of space, trains the patient to compensate spatially.
