I'm a clinical neuropsychologist, and part of the work that I do is intra-
operative cortical mapping.  That's where a patient undergoing brain surgery
(e.g., for resection of a seizure focus or a tumor) is given a local instead
of a general, and is kept awake during the procedure.  Prior to removal of
tissue, the surgeon stimulates regions of the cortex (creating a temporary
"lesion") while I test various cognitive and neurological functions.  One of
the most important functions that we test is language, and one of the most
sensitive tests of language (at least in terms of post-operative deficits) is
naming.

Unfortunately, we've been unable to test naming in our patients because some
of the equipment used during the surgery (specifically, the sterotaxic ring)
blocks the patient's eyes.  What were looking for is some sort of goggle that's
relatively thin (1-2") that would allow us to directly or indirectly present a
visual stimulus to the patient.  Something that could be driven from a PC would
be especially nice.  We've already got a PC in the operating room (plus a Sun
workstation that I'm not so familiar with).

Has anyone ever heard of, or seen, or used anything that might be of use?
If you have, please respond via email, since I don't get on this list on a
regular basis.
