Prospect
on manpower vision
When eyeball was damaged and
lose sense of light completely, we are unable to help the
sufferer to recover their eyesight in term of the technique
at present. The thought that creating the manpower vision
has bestired numerous scientist to explore and attempt. Stimulating
nerve center of vision by electricity is the earliest attempt
which also completely conform with logic. The earliest observation
on the wake up of cerebra cortex of human beings by stimulation
appears at the second decade of twenty century.
There is a report from German surgery
scientists said that dot stimulation on the side-glance cortex
will produce stillness dot sense of light on the opposite
side. And the similar thougt supposed by Show in 1995 that
transiting the light from the electric eye to electricity
stimulation and carrying it out to the electrode of the cerebra
pillow foliage cortex has been aroused maximum attention from
society and obtained patent from U.S.A. One research in years
of 60 demonstrates that one sufferer with hand hold electric
eye can follow light by transformation of the light signal
to electricity stimulation and carry it to the cortex of vision
via lead. And the researches thereafter approved that different
stimulation can correspondingly produce the heteroptics of
light.
These scientist expect to accomplish
the ultimate ideal false retina system include one camera
which is fixed in the glasses and one equipment which can
be called double charge. Camera utilize one eletron similarity
to capture visual image, and use double charge equipment to
take photograph. Double charge equipment will tranform image
to data information, and transfer the data information via
laser to the object planted by retina, and this object will
utilize one attachable electrode series to transform laser
pulse to electron signal form. Theoretically speaking, these
electron signal then stimulate the closest ganglion cell,
and the ganglion cell will cascade the informantion to visual
nerve and cerebra, and thus make the sufferer have the ability
to feel image. If everything can smoothly proceed according
to the plan, this technique can be applied to eyes of human
being in 5 to 7 years. The realization of manpower vision
will be one significant technical breakthrough including many
courses such as biology, engineering and computer which will
bring the revolution of biology research.
