When Karen Ann Quinlan was autopsied, the most prominent neuronal loss
was found not in neocortex (as expected), and not in the brain stem
(as is also common in comatose patients), but in the thalamus--and not
the reticular parts.  Get the picture?  (If you don't get the picture,
read up on the functions of the thalamus.)
