Is the colour you see the same as what I see? It’s a question that has puzzled both philosophers and neuroscientists for decades, but has proved notoriously difficult to answer… Now, a study that recorded patterns of brain activity in 15 participants suggests that colours are represented and processed in the same way in the brains of different people.

The researchers found that in most cases they were able to predict which colour was being viewed by a participant in this second group, using the patterns of brain activity they had seen in the first group. They also found that different colours were processed by subtly different areas within the same region of the visual cortex, and that different brain cells responded more strongly to particular colours. These differences were consistent across participants.

The paper on Journal of Neuroscience (sadly not open access): https://www.jneurosci.org/content/early/2025/08/29/JNEUROSCI.2717-20.2025


My critique is… the researchers are based in Tubingen, Germany, and I assume most of their 15 participants are of European cultural heritage (cannot verify… no open access). I would love to see if they can replicate this in a more multi-cultured setting. Some Asian cultures have rather different verbiage for different colors, and I wonder whether that would bias ppl’s perception.

      To give them credit… neuroscience and scanning ppl’s brain is expensive lol. But yeah, 15 participants and no open access, I have no clue exactly what or how they did this

          I thought it was cost of electricity and maintenance of the machines? How much money is compliance for these things?

            $1 for electricity, $2 for the tech, $5 for the machine. $.50 for the researcher, and $25000 for the owner of the facility.

              Your numbers must be wrong. The average cost of an MRI scan is under 1000 dollars in the States, uninsured. Link

              This is for a 4 hour procedure, so the values given for labor are also criminally low. I know machine techs who are well paid and work on less than 35000 machines a year.

                The fact you didn’t detect my hyperbole proves my point. Those numbers were in fact completely made up.

                  If your point is just that people on the Internet aren’t very literate, your point is not interesting. Too much misinfo from ‘hyperbole’, save it for the discord imo. We have AI to automate vibe numbers now.
