How is a number represented in the visual system according to the example?

• A. Through neuron activation in the eye
• B. Stored in the liver
• C. In the bloodstream
• D. In the bones

Answer: (A)

Numbers in the visual system are represented as patterns of neuron activation that begin in the retina. Light is detected by photoreceptors, which convert it into electrical signals that travel through the visual pathway. The resulting activation across populations of neurons encodes the quantity being viewed, and the brain interprets this distributed activity to perceive the number. This neural activation in the eye and along the visual system is how the visual system represents numbers, not storage in the liver, bloodstream, or bones.
