Brand-new colour created by tricking human eyes with laser

Five people have been able to feel the color after researchers use lasers and tracking technology to activate some cells in their retains. The color of the blue green color is the severity of the colors, or ‘saturated’, or ‘saturated’.

The work is “amazing technically” and an “extraordinary success,” says Kimberley Jameson, a Colore of Calore Vision scientist at the University of California, Aryan.

This is not the first time that researchers have stimulated individual cone cells – the eye photovirusters that indicate the brain color. But this time it was done in an area that was quite substantially to change a person’s vision. “What is the novel in this study is proof that such new colors can be understood,” says Sergio Nassimanto, a physicist who specializes in a human point of view at the University of Minor, Portugal’s Briga.

Charts off severe

Researchers, who published details of this technique Science development On April 18¹Otherwise, the inaccessible color is called ‘الو’. California University, Berkeley’s computer scientist and vision researcher, Ren NG says it is like a peacock’s blue or tea, “but the saturation level is far from the chart”.

This method is run by software driven by the name of dumbs and wizards – controlling the same doses of light delivered to each cell in the retina, so that the brain uses to translate color color or has never experienced signals before.

The NG says the technique has the ability to produce other new colors. It can also allow people with colorful blindness, which has no effective treatment, which can be felt in color that they will not be done otherwise.

It will have a lot of work. So far, the team can carefully control the color in just a small view – which is almost doubled to cover the moon in the sky – and this procedure requires very few labs available for technology. Jenny Bostin, a visual neuro scientist at the University of Sussex, UK, Britain, says, Even if it is not applied, the research is “an impressive technical success.” “There are a lot of possibilities for future research using techniques.”

Fingerprints of light

The human color approach comes from the brain from which it compares the signal, which combines the three types of light detection cone cell. Each wavelength is sensitive to different but over -liping range. In short, blur wavelength, S cone is the most responsible, while M, or medium, cone is activated with the most green light. The cone is higher than the red light of long wavelengths than others. Every color that a person can see comes as a feature of activating these three cell types in the brain, according to a fingerprint or coordinated set.

Since M cone is in the middle of the spectrum, activation of light also triggers a neighbor S or Lin cone. The NG and his colleagues wondered what, if M -cone itself encourages itself, it will create a new color.

Using a technique developed by co -authors at Washington University in Seattle, the team first made a map of each trial partner’s retain, marked each cell position and type.². This allows them to track the movement of each person’s eyes and train the laser lights on individual cone cells.

He then encouraged only M cone with laser light microdosis. To examine what the participants are watching, the team asked them to meet the color they understood with examples of the same wavelength. There was no match-it seemed that the color of olo was more intense than the most vibrant blue green in the usual point of view. NG says participants had to add white light to ‘wash’ to ‘wash’ so that it could match the nearest natural color.
