In a prior post, The Paradoxical Brain, we mentioned that in acquired brain injury, or ABI, patients typically experience damage to the right hemisphere which results in hemispatial neglect or inattention in the left visual field. The left hemisphere, which directs the right visual field, is typically involved in sustained, broad, open attention characterized by vigilance and alertness. The right hemisphere, which directs the left visual field, is characterized more by narrow, sharply focused attention to detail.
