completely different folks’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 tough to reply.

Now, a examine 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 folks. The findings had been printed within the Journal of Neuroscience on 8 September¹.

“Now we know that when you see red or green or whatever colour, that it activates your brain very similarly to my brain,” says examine co-author Andreas Bartels, a cognitive neuroscientist on the University of Tubingen and the Max Planck Institute, each in Tubingen, Germany. “Even at a very low level, things are represented similarly across different brains, and that is a fundamentally 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 folks.

The pair used practical magnetic resonance imaging (fMRI) to match exercise within the brains of a gaggle 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 educated a machine studying mannequin referred to as a linear classifier on this knowledge, and used it to foretell which colors had been being considered by members of a second group of examine individuals, on the idea of their mind exercise.
