WebFeb 4, 2024 · Light enters your eye and stimulates the cone cells when you look at an object. Your brain interprets the signals from the cone cells to help you determine the color of the object. The red, green and blue cones work together to create the color spectrum. For example, when the red and blue cones are simulated in a certain way, you will see purple.

Retina: Anatomy, Function & Common Conditions

In vertebrates, activation of a photoreceptor cell is a hyperpolarization (inhibition) of the cell. When they are not being stimulated, such as in the dark, rod cells and cone cells depolarize and release a neurotransmitter spontaneously. This neurotransmitter hyperpolarizes the bipolar cell. Bipolar cells exist between photoreceptors and ganglion cells and act to transmit signals from the photore… WebMar 8, 2024 · The lens is an ellipsoid structure located in the eyeball.
