Sensation: Vision

Retina

The light sensitive inner surface of the eye

Rods

Photoreceptor cells that are responsible for vision in low light conditions

Cones

Responsible for color vision

Fovea

Area of the retina responsible for sharp central vision

Blind Spot

Area on the retina where you are unable to detect something

Ganglion Cells

Neurons that receive visual information

Lens

Focuses light on the retina

Accommodation

The process by which the lens changes its shape and focus

Transduction

When photoreceptor cells convert light into signals for the brain

Trichromatic Theory

Theory proposing that color vision is based on three different receptors

Opponent Process Theory

Theory proposing that color vision is based on pairs of opposing colors
