To Explain:

Propose a way to study the function of the rods alone, given they can sense light about 1000 times dimmer than the cones.

Explanation

Introduction:

The retina has two main photoreceptors called rods and cones. Rods are 100 times more sensitive than cones but do not perceive color. However, they are responsible for peripheral vision and motion detection.

One of the most important characteristics of the rods is that they are sensitive to dim light, even in dark places they can perceive some objects in gray scale. One way to study the rods in isolation is to observe and analyze their behavior in the dark by turning on and off very dim lights that are imperceptible to the cones and set them in motion to evaluate their response...
