The signals that colors create in our brain can tell us something without the need for any text or words. While it is known that the color red has a stimulating effect, scientists also gave a surprising answer to the issue of what the color red causes in our brain.
In the study, published in the journal eLife, scientists examined whether the color red actually triggers brain waves more strongly. The study focused on the early visual cortex known as ‘V1’. This cortex was the largest visual area in the brain and the first to receive input from the retina.
Red does not have an effect on the brain as we think:
Unlike other studies, the scientists used a different method to see how a color affects the brain. In the study, he examined the gamma fluctuations that occur when we perceive a color in the brain, using ‘magnetoencephalography’, a method to measure the magnetic activities of the brain. 30 volunteers participated in the study.
The result was quite interesting: Red, which is known to have a big impact on our brain, actually produced a gamma fluctuation of the same intensity as the green color. As for the color blue, previous research was reconfirmed: it was the color that elicited the least neural response in the early visual cortex.
