Blindsight and Rage  JoRoss joross at Mon Jul 26 00:14:13 EST
1999  Hi. I've got a couple questions, and I'm hoping you can
help.  But I know nothing about neuro-anything, and I'm afraid
this is going to be like asking for directions in a foreign
language--when you get the answer, you don't understand it.
Anyway, I'm a writer, looking for just a bit of truth with which
to temper my lies ... er, fiction. I don't even know if both
these questions fall under the neuroscience rubric, but here
goes:  1 - Blindsight. I read a paragraph about this, and it
looks like an interesting hook for a story I'm working on. But I
don't know: what causes it (stroke, brain lesion--if there is
such a thing--head trauma, etc.), if it can occur in the
complete visual field (I read about it on one side only), and
how people who have it deal with it. If I understand blindsight
(probably not), it seems that your subconscious (or unconscious)
can see, but you cannot consciously "see" what you're seeing--
you are, effectively, blind. Tr
