Scientists have documented the first known case of a person born without the ability to recognize human voices
Your phone rings. But when you pick up, you don't recognize your mother's voice on the other end. It's not amnesia, but phonagnosia -- the inability to recognize voices. If you've never heard of it, that's because it's a very rare condition that usually occurs after a stroke, as a result of lesions in the right hemisphere of the brain. This week, however, scientists at University College London (UCL) reported the first known case of a woman born with phonagnosia in the online journal Neuropsychologia.
