How Your Eyes Send Images to the Brain 1 Color Vision. There are two distinct kinds of cells in the eyes, the cones and the rods. … 2 Night Vision. Rod cells are used for low light conditions. … 3 Signal Transmission. Signals from the cone and rod cells are passed on to neurons which eventually come together to form the optic nerve.
Once the signals are sent to the brain they are processed by the visual cortex, which is located in the back of the head. This part of the brain takes all of the signals from the eye and turns them into images. There are two distinct kinds of cells in the eyes, the cones and the rods.
These nerves serve as the main “connectors” between the retina and the brain. Each optic nerve starts at its corresponding eye. However, midway through their journey to the brain, some of the axons in the optic nerves cross over at a specific location, called the optic chiasm (cue my sister’s confusion).
