Spatial recognition and spatial order memory in patients with dementia of the Alzheimer's type.

abstract：:While skilled readers produce an increased and left-lateralized event-related-potential (ERP) component, known as N170, for strings of letters compared to strings of less familiar units, it remains unclear whether perceptual familiarity plays an important role in driving the increased and left-lateralized N170 for pri...
