Anomia for facial expressions: evidence for a category specific visual-verbal disconnection syndrome.
We describe a patient with a selective impairment in naming and pointing to emotional facial expressions following damage to the right temporal lobe. His language functions were otherwise intact, and he performed well on a variety of perceptual and associative emotional facial tasks. We propose that his inability to match facial expressions with their names was induced by a disconnection between visual semantic and verbal semantic representations for facial emotions.
