At the level of the retina and brain,which colour vision theory is supported

Question

Quizplus · Accepted Answer

The opponent process theory is supported at the level of the retina and brain. This theory states that there are three types of cone cells in the retina that are sensitive to different wavelengths of light: short, medium, and long. These cone cells send signals to the brain, where they are processed by opponent cells. Opponent cells are neurons that respond to the difference between the signals from two different cone cells. For example, one type of opponent cell responds to the difference between the signals from the short-wavelength and long-wavelength cone cells. This type of opponent cell is called a red-green opponent cell.
