The rear surface of the eye, which is lined with visual receptors.
The part of the world that you see.
An opening in the center of the iris.
Exits through the back of the eye.
Abundant in the periphery of the human retina and respond to faint light but are not useful in daylight because bright light bleaches them.
Abundant in and near the fovea, are less active in dim light, more useful in bright light, and essential for color visions.
The ability to respond in limited ways to visual information without perceiving it consciously.
Inferior temporal cortex
Cells located in this part of the brain respond to meaningful objects.
Chemicals that release energy when struck by light.
We perceive color in terms of opposites.
Color vision deficiency
Otherwise known as colorblindness.
According to this theory, we perceive color through relative rates of response by three kinds of cones, each one maximally sensitive to a different set of wavelengths.
Negative color afterimage
A replacement of the red you have been staring at with green, yellow, and blue with each other, and black and white with each other.
Lateral geniculate nucleus
Most ganglion cells go to this part of the thalamus.
Primary visual cortex
Information from the lateral geniculate nucleus of the thalamus goes to this part of the brain.
An inability to recognize objects despite otherwise satisfactory vision.
The point where the optic nerve leaves the eye; there are no receptors here.
A tiny area specialized for acute, detailed vision.
Impaired ability to recognize faces.
An area in visual space that excites or inhibits a particular visual cell.
Located closer to the center of the eye, these cells send their messages to ganglion cells.
These cells' axons join together and travel back to the brain.
The ability to recognize colors despite changes in lighting.
The cortex compares information from various parts of the retina to determine the brightness and color for each area.
