Dear list, Thank you all for your responses to my post. Colette's point is very well taken. So -- IF we can eliminate non-auditory sources of information leaking through the system (consciously or unconsciously) in this case, it might be quite interesting. The patient is not 100% sure that her deafness is cochlear in origin, and she hasn't had any scans done as yet. The patient says that she does lipread, but that she's pretty sure this phenomenon occurs whether she's getting visual info or not. It would be really weird if the deafness was cochlear AND there was no non-auditory source of information....Otherwise, as Walt and others point out, a neuropathy at a higher stage (cortical maybe) might explain it. I don't know much about blindsight, but from my graduate school course in vision, what I remember is that the patients can point to the source of a light but don't get much more sensory input than that, is this true? I also vaguely remember that the visual saccade pathways (superior colliculus) might be involved in blindsight....In our present case, the patient seems to be getting a lot of information, requiring quite a bit of detail in the sensory input... If any of you would be interested in pursuing this further with the patient, please email me for her contact info. Happy New Year!
