title: The neurophysiology of failed visual perceptions: some implications for medical teaching.
abstract: Failed perceptions of clinical abnormalities may have a neurophysiological explanation including three major covert eye problems and seven major brain-processing problems. Seven suggestions are made in an attempt to minimise their effect. We see in detail much less than we think and there is no substitute for seeing real-life clinical abnormalities.
