completely different individuals’s brains course of colors in the identical manner

Is the color you see the identical as what I see? It’s a query that has puzzled each philosophers and neuroscientists for many years, however has proved notoriously troublesome to reply.

Now, a research that recorded patterns of mind exercise in 15 individuals means that colors are represented and processed in the identical manner within the brains of various individuals. The findings had been printed within the Journal of Neuroscience on 8 September¹.

“Now we all know that whenever you see purple or inexperienced or no matter color, that it prompts your mind very equally to my mind,” says research co-author Andreas Bartels, a cognitive neuroscientist on the College of Tubingen and the Max Planck Institute, each in Tubingen, Germany. “Even at a really low stage, issues are represented equally throughout completely different brains, and that may be a basically new discovery.”

Bartels and his colleague Michael Bannert wished to discover how completely different colors are represented in elements of the mind related to imaginative and prescient, and the way constant that is throughout completely different individuals.

The pair used useful magnetic resonance imaging (fMRI) to check exercise within the brains of a bunch of individuals whereas they considered completely different colors. This allowed them to create a map of mind exercise that confirmed how every hue was represented neurologically. They then skilled a machine studying mannequin referred to as a linear classifier on this information, and used it to foretell which colors had been being considered by members of a second group of research individuals, on the premise of their mind exercise.
