Ontario researcher, a new color that can cause treatment for dalonism and degenerative diseases of the eye, has set a discovery.
“We managed to stimulate only part of the eye”, “The author of the neuroobiologist Austin Roora, the author of the research broadcast in April in April Berkeley University” Heurobiologist Austin Roodyda ” Science advances.

Normally activated non-activated photorecots. It is normally corresponding to a green color. It’s really a new color.

The retinal of the eye, each of the six million “cones”, which takes a different wave length to fit a different color, contains photographers. Three category cones, medium and short. Mr Roorda’s stimulated cones are in the middle category. However, the average cones are never stimulated in the absence of isolation, but also together with the cones of long or short categories. This means that the wavelength of the average cones – the color they seize – is never “seen.”
“The purpose of this practice can use the brain to create new sensation information? If so, it means that this is the plasticity of the brain. It is encouraged to treat visual problems,” he said.
In the green registry
But is it really a new color?
“It’s the same difference between red and pink,” said Mr Roora. Most people would say that these are two different colors. Something certain is not seen by a green man. Green with a little less white. “
Mr. Roora is also stimulating 4,000 cones in the retina. 250 cones were stimulated during the experiment that determines this new green.

This device only allows you to stimulate the average cones of the eye only.
Among the 5% and 10% of the cones are the middle and long cones. “There is twice a large and middle cone, but there is a change from one person to another,” he said. I have 1,3 times longer cones from the average cones, but there are three times longer cones from a colleague’s average cones. Three types of cones are distributed in the retina.
Short cones usually draw wavelengths around 440 nanometers (NM) to suit a purple blue. Vehicles around 535 nm are in line with the greenignity. 559 Nm Wave lengths, go to red from orange. By comparison, Mr Roora shows that the yellow color is suitable for the wavelength.
Everyone would agree to call yellow on both sides of 589, as yellow between 4 and 5 nm.

The “spectral sensitivity” of short and long cones coincide, ie no natural light can not stimulate only the average cones.
The new color detected by Austin Rooor is in line with 510 NM wavelengths.
Boring
Discovery, red and green can contrive the opposite of dalonism. This disorder, now called “dichromatism”, causes the lack of long or average cones. “Probably only stimulates certain cones, he can cultivate the brain to realize another color,” he said. Another step to create incomplete cones can be a gene therapy. ”
Mr Roora believes that there may be a color when there are fewer cones than normal than normal.
Daltonism affects 1% of men and is very rare in women. About 8% of men have a form of small dichromatism. Some women are between 1% and 10%, and even “tetrachromatic”, that is, there are four types of cones. “These are two different long cones, because it is not easy without testing,” the researcher notes.
This technology can also be used for other degenerative eye diseases such as a pigmentary retinitis in the beginning of adulthood, and the tunnel vision associated with the violation of cones. Touch one of 5,000, so 1500 Quebecer, it is hereditary.
Is the number of cones decreases with age? “It’s not much. I imagined my cones for a longer term in the planet. In 1996, I was lucky in the world’s first laboratory.
The ambition of the scientist is to stimulate the cones of Fovea used for accuracy. “Fovéa is only 100 micrometer, which includes the highest density of cones. I hope to reach there before I scholarships.
Visually Nocturne
There is a fourth species photorecotor type called “Stick”. It is used for night vision and more – there are 100 million sticks in the eyes – three types of cones are more than cones. “The sticks are very sensitive and therefore they are not very useful from the day, because they sat very quickly,” Mr Roorda.
