00:00The truth about colors. Do we all see the same thing? For a long time?
00:05The question of whether we all perceive colors in the same way has been one of philosophy's most intriguing puzzles.
00:12Now, neuroscience has entered the discussion.
00:16In a recent study published in the Journal of Neuroscience,
00:19neuroscientists Andreas Bartels and Michael Bannert have shed new light on this mystery,
00:25and their answer is a resounding maybe.
00:27To understand their research, you must first consider the two main theories about how the brain processes color.
00:35The first is that every brain is unique, and that the perception of red, for example,
00:40would activate a network of neurons that is completely different for each person.
00:44The second, which the study by Bartels and Bannert has managed to demonstrate,
00:50proposes that seeing the color red, or any other,
00:53triggers a pattern of brain activity that is surprisingly consistent among individuals.
00:58To reach this conclusion, the researchers monitored the brain activity of 15 people,
01:03while showing them different shades of red, green, and yellow.
01:07By analyzing the data, the team was able to predict which color each person was seeing
01:12based solely on the pattern of their neuron activity.
01:14This means that, at the level of brain activity, there is a great similarity in the way we all process colors.
01:22According to Bartels, there are commonalities across brains.
01:26However, this is where science hits the limits of philosophy.
01:30The research by Bartels and Bannert can tell us that our brains process color in a similar way.
01:35But it cannot answer the fundamental question of what it feels like to see the color red.
01:40The study cannot reveal whether your subjective internal experience of seeing the color red is identical to mine.
01:47The question of how brain activity generates our conscious experiences remains one of the greatest challenges in science.
01:55While this study has brought us one step closer to understanding the mechanics behind our vision of color,
02:01the philosophical mystery of subjective experience of consciousness persists.
02:07And it is a question that will undoubtedly continue to be debated for a very long time.
02:13The human brain continues to be one of the most fascinating frontiers of science.
02:18And, as we see, each answer leads us to a new and deeper question.
