Re: [Yasmin_discussions] Multisensory Perception

It be timely to consider the little-known embedded bodily sense of
Proprioception where the briain maps the orientation and movement of our
body and limbs-especially in an age of mobile phones armed with compasses
and accelerometers-the case of Ian Waterman should give us all pause when
discussing multisensory perception:

*Loss Of Proprioception- The Case of Ian Waterman *

*At the tender age of only nineteen, Ian Waterman became sick with a viral
diarrhoea which slowly began to diminish his co-ordination. When he was
eventually taken into hospital, he was initially thought to be drunk; his
speech had become slurred and he could neither walk nor maintain an upright
position. Things, from then on, progressively became worse, culminating at a
stage where he no longer had any control whatsoever over his own bodily
movements.The virus had cause him to lose all sense of touch and
proprioception from the neck down. He could initiate a movement but did not
have any control over it or where it happened. All of the large sensory
nerves and receptors had been destroyed and, as such, were no longer sending
the relevant information to his brain to maintain and update his body
schema. This meant that he could be lying on the bed and yet not feel his
body at all, and if he did not look at them, he could not tell where his
arms or legs, or any other part of his body, were at any given time. *

*Through constant concentration and visual input, Ian Waterman, slowly
learnt to move again. He was able to do so by planning, and concentrating
on, every movement his body had to make in order to produce the desired
action. However, in doing so, he found he could only do one thing at a time.
It took so much concentration just to move one leg, that he could not move
his arm simultaneously, for then the concentration would have to shift to
his arm, and he would lose control of his leg. Moreover, if he was to, shall
we say, hold an egg, he could not walk at the same time. His concentration
would have to shift to the act of walking and would, in turn, leave nothing
for the task of holding the egg. Without being able to concentrate on the
act of holding the egg, it would either be crushed or dropped.*

*Ian Waterman never fully recovered but did learn to deal with his problems
in a rather incredible way. He can walk, drive, and maintain a normal job.
However, the above problems still stand and every action is the result of
unfaltering planning and concentration. Simple movements and sensations,
that we are normally unconscious of and that we all take for granted,
suddenly become very complex without proprioception as this case clearly
shows. *
