Hi

Bryan Kolb of Kolb and Wishaw described his own experiences of a stroke
in the following article:

Canadian Journal of Psychology, 1990, 44(2), 130-147
Recovery From Occipital Stroke: A Self-Report and an Inquiry
Into Visual Processes
Bryan Kolb
University of Lethbridgc
ABSTRACT This report summarizes the behavioural effects of a right
occipital stroke
in the author. An upper left quandrantanopia resolved over the first 50
poststroke
days to leave a scotoma that included the left upper quadrant of the
liwea and extended
upwards about 6* and lateral about 15". There was no further reduction
in size
over the next 4 years. In the early stages of recovery there was an
inability to detect
consciously either the presence of objects or their motion, except upon
reflection
once an object entered the intact visual field. This has been referred
to previously
as blindsight. On about the fourth day poststroke, part of the scotoma
became visually
active, pnxlucing a scintillating aura, which remains. Shortly
thereafter colour perception
returned in the scotoma, as did motion detection. Although there was
little
additional change in the field defect after 2 months, the author's
visual abilities have
continued to improve, in large part because of a shift in fixation such
that information
at the centre of the visual field now falls about 1.5* into the lower
right portion
of the fovea. The implications of the visual and behavioural changes
are discussed
in the context of multiple visual systems and with respect to recovery
of function.

Take care
Jim

No stroke to blame it on but I was just reminded by someone on the
list, Jill's response wasn't, "Neat!" but "This is so Cool!" I don't
think I'd have faired any better with more words though. ;)

Chris et al- 
I don't know how many of you remember the story but several years ago,
Dr Jill Bolte Taylor suffered a major stroke (neuroanatomist).
Originally, if memory serves, she suffered profound loss of language and
other left-hemisphere functions. She has since developed a number of
talents that she was previously unaware of including making stained
glass sculptures and of "anatomically correct" brains. See:
http://drjilltaylor.com/brains.html for her web-site. There is also a
book on her story titled, "My Stroke of Insight: A brain scientist's
personal journey". 

She was the one seen on video (Nova?) relating her experience the
morning of the stroke- at one point she has the thought, "So this is
what my patients have been experiencing. Neat!" I can only admire or
wonder at that level of scientific curiosity in such a time of tragedy.
I fear my one word response wouldn't be repeatable on list! :)
