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.
