What areas of our brain represent the colors we see?

Red, orange, yellow, green, blue, indigenous and violin: The rainbow colors are known to anyone who remembers “Roy G. Biv”

However, scientific research has long shown that such colors are not natural for the physical world, but rather a result of the way our brains process light, the gold portal broadcasts.

The study noted that the “connecting a knot is an ancient and often conducted human action, which is the incarnation of daily procedural knowledge, making it an excellent goal for investigations.

” A new study, coauthored by a neuroscientist of the University of Chicicago, identifies those nerve networks, especially brain areas that codify the colors we actually see.

“We have been able to show where it happens on the visual path, which is relatively early,” said Prof. Steven Schevell, a leading researcher on color perception and brightness.

It's like a road map showing where to look for nerve circuits that cause passage from the earliest nerve representations of the physical world in our mental world. ”

Using brain scans and a new “section of rivalry”, he and his co-authors discovered that primary visual cortex, which is the first phase of quantum visual processing, does not accurately represent the colors that we try. On the other hand, higher areas on the visual path follow the overtones that we actually see. The work was published in the National Academy of Sciences proceedings. Based on their previous work by the Chevell laboratory, they conducted their experiments with a technique that was backed quickly and forward between the two different lengths of light. Although the change occurred six times a second, viewers saw a stable (multiple) color for seconds before their perceived color was moved to another color.

After reviewing FMRI scans, Schewell and his colleagues discovered that activities in the highest parts of the visual corthex were those that conformed to the colors of their study of colors. These results mark an important step in explaining the passage from the encryption of physical light that enters our eyes in our perceptive experience of color vision.

It's always satisfying to do a great job that none of the collaborators could do alone,” said Schewell, Dating Service Professor Hastings Moore of Psychology, Ophthalmology and Visual Science.

Chevell, who heads the UChicago Institute for Mind and Biology, had previously published on the use of the interrupted rivalry in a 2017 paper, a coauthor with Anthony DéAntona, PhDâ10, and former UChicago Jens Christianen postdo.

That job revealed a similar phenomenon of color perception, but it did not identify which areas of the brain were responsible.

Now, Chevell hopes that these new findings can lead to research explaining how different regions of the visual path realise the transition to human color perception.
