In the neural pathways connecting the eye to the brain, there are neurons that respond primarily to each of the following light patterns except ________.
A) orange-violet
B) black-white
C) yellow-blue
D) red-green

Question

Quizplus · Accepted Answer

The neurons in the visual system have cone cells that respond primarily to three different types of light wavelengths - short (blue), medium (green), and long (red). These three types of cones respond to light patterns that include black-white, yellow-blue, and red-green, but not orange-violet, which is a combination of medium and long wavelengths that cannot be distinguished by the cones. Therefore, option A (orange-violet) is the correct answer as there are no neurons that respond primarily to this light pattern.
