Light and Visual Stimuli
Variety of a color; tint.
What is hue?
The opening in the center of the iris; appears black.
What is the pupil?
This part of the eye is colored. It contains muscles that can control the size of the pupil.
The only part of the electromagnetic spectrum that humans can see.
What is visible light?
A form of electromagnetic energy; something that makes vision possible.
What is light?
The white, outer part of the eye that helps to maintain the eye’s shape and protect it from injury.
What is the sclera?
Nerve that is located at the back of the eye and functions in carrying visual information to the brain for processing.
What is the optic nerve?
The simultaneous distribution of information processing across multiple neural pathways; the ability to process "what?" and "where?" at the same time.
What is parallel processing?
The richness of a color stimulus.
What is saturation?
Located behind the eye; this part of the eye responds to light and records electromagnetic energy which is then converted into neural impulses for the brain to process.
What is the retina?
The flexible disk-like structure that brings the eye’s images into focus.
What is the lens?
The integration of what is being processed by different cells and neural pathways
What is binding?
Light travels through space in waves. This is the distance between two waves.
What is a wavelength?
The clear membrane in front of the eye that helps bring images into focus.
What is the cornea?
These are receptors inside the retina that are light sensitive.
What are rods?
Neurons in the brain’s visual system that respond to particular features of a stimulus.
What are feature detectors?
The height of waves of light.
What is amplitude?
These are receptors that are used for color perception.
What are cones?
About how many receptor cells does the human retina have?
What is 126 million?
This is the place on the retina where the optic nerve leaves the eye on its way to the brain.
What is the blind spot?
