As the video progresses, different pathways appear, each of which is involved in a distinct process in the brain. The colors of the fibers indicate the direction in which they send signals: fibers ...

Even though the human visual system has sophisticated machinery for processing color, the brain has no problem recognizing ...

There, those reflected wavelengths are transformed into electrical signals to be interpreted by our brain. So we don’t really “see” colour, but reflected light, as interpreted in our brain.

This causes a bit in your brain to be set. The result of this is the ability to detect these patterns and indicate the detection of one of the adapted patterns by seeing its complimentary color.
