Damage to this area causes: deficits in perception and memory of spatial relationships; apraxia; hemispatial neglect (right side only) Receives input from 3 sensory systems (vision, auditory, somatosensory) Hemispatial neglect-not able to see parts of their world or pay attention to half of their vision: avoid obstacles, but don"t consciously see what is in their view.
