If your mother had x-ray vision and eyes on the back of her head that saw everything, it’s probably because her body’s innate intelligence knew she ate a lots of red foods whose properties nourish the eyes and vision. The practice of Traditional Chinese Medicine (TCM) teaches the Five Element theory, where each element relates to a season, flavor, color, organ, bodily system Continue reading

CHICAGO – While the brain is attuned to link a color with a particular object, researchers have found that the familiarity to color stays with the brain separately, and it can assign it to some other object.

The researchers at the University of Chicago have for the first time found that the brain processes the shape of an object and its color in two separate pathways, and, though the object’s shape and color normally are linked, the neural representation of the color can survive alone.

When that happens, the brain establishes a new link that binds the color to another visible shape.

“Color is in the brain. It is constructed, just as the meanings of words are constructed. Without the neural processes of the brain, we wouldn’t be able to understand colors of objects any more than we could understand words of a language we hear but don’t know,” said Steven Shevell, a University of Chicago psychologist who specializes on color and vision.

The study expands the understanding of how the brain is able to integrate the multiple features of an object, such as shape, color, location and velocity, into a unified whole.

“An aspect of human vision that we normally don’t appreciate is that different features of an object, including color and shape, can be represented in different parts of the brain,” said Shevell.

If a person sees a basketball coming, it is perceived as having a particular color, shape and velocity.

“The knitting together, or what can be called ‘neural gluing,’ of all those different features so we see a unified object is a complex function done by the brain. Our research focused on how the brain does that,” explained Shevell.

For the study, the researchers used a technique called binocular rivalry, which presents a different image to each eye and thus pits signals from the right eye against signals from the left.

“The brain has difficulty integrating the two eyes’ incompatible signals. When the signals from the two eyes are different enough, the brain resolves the conflicting information by suppressing the information from one of the eyes. We exploited this feature of the brain with a method that caused the shape from one eye to be suppressed but not its color,” said Shevell.

Firstly, they showed subjects vertically oriented green stripes in the left eye, and a horizontally oriented set of red stripes in the right eye.

“The brain cannot fuse them in a way that makes sense. So the brain sees only horizontal or vertical,” said Shevell.

They developed a new form of the technique that allowed the horizontal pattern to be suppressed without eliminating its red color, which continued on to the brain.

At this point, the brain has a musical chairs problem-both the red and green colors reach consciousness but with only the one vertical pattern-one object but two colors.

The surprising result was that the “disembodied red, which originated from the unseen horizontal pattern in one eye, glued itself to parts of the consciously seen vertical pattern from the other eye.

That proves the idea of neural binding or neural gluing, where the color is connected to the object in an active neural process,” said Shevell.

The study has been published in Psychological Science.
