Six patients who give many years suffered serious limitations from the sight (in great legal blind part) have repurchased in part the precious sense thanks to the system of one artificial hairnet to the silicon in the fed course of one experimentation on a new one chip to solar energy, created from the society American Optobionics di Wheaton, in Illinois.  | | Alan Chow |
The microchip, that it comes inserted surgical behind the hairnet, is smaller than one capocchia of pin, and often the half of a paper sheet: the operation principle is simple, and previews the conversion of the luminous stimuli in impulses electrical workers: "we are trying to replace the function of the fotorecettori" explains Alan Chow, the oculista pediatra to head of the experimentation that has developed the chip with the Vincent brother, that she is engineer electrical worker. 
The loss of the able receivers to convert naturally the light in nervous impulses is typical of diseases as retinite pigmentosa and the degeneration to maculare, that they represent the main causes of incurabile blindness and hit all over the world approximately 20 million persons. 
Al.di.là.del recovery directly legacy to the chip, the investigators has found that the system seems to favor also the recovery of the activity from part of the cells limitrofe. It turns out you of this study have been introduces in Florida to meeting the anniversary of the Association American to you for the searches on the vision.
