Patients experiencing spatial hemineglect ignore one side of their environment (usually the left side) in multiple modalities. This deficit often occurs as part of severe brain trauma, usually to the right part of the brain, particularly the parietal lobe. An interesting research question concerns the precise "definition" of what constitutes the left half of the patients' experience. Is it the position in the visual field, the perception of the left half of the body, or is it related to individual reference systems that are object and task specific? In her research, Dr. Behrmann has attempted to answer some of these questions.
