How to Create and Use Binocular Rivalry
Published on: November 10, 2010
Summary
Binocular rivalry, the perception of one target over another, is tritanopic. This means the brain
Area of Science:
- Visual neuroscience
- Color vision research
Background:
- Binocular rivalry is a phenomenon where perception alternates between two different images presented to each eye.
- Understanding the sensory mechanisms underlying binocular rivalry is crucial for visual neuroscience.
Purpose of the Study:
- To investigate the role of color information in binocular rivalry.
- To determine if the binocular rivalry mechanism is sensitive to color differences.
Main Methods:
- Measured exclusive visibility time for colored targets in trichromats and red-green dichromats.
- Used black and colored square-wave gratings (3 c/deg, 1-degree diameter) as targets.
- Analyzed the relationship between color difference and exclusive visibility time.
Main Results:
- In trichromats, exclusive visibility time increased with greater color differences between targets.
- Red-green dichromats showed no effect of color difference on exclusive visibility time.
- These findings suggest a color-opponent mechanism in binocular rivalry.
Conclusions:
- The binocular rivalry mechanism appears to be tritanopic.
- It is primarily responsive to color signals from medium- and long-wave-sensitive cones.
- This implies that blue-yellow color opponency, not red-green, drives rivalry.

01:32The Retina
The retina is a layer of nervous tissue at the back of the eye that transduces light into neural signals. This process, called phototransduction, is carried out by rod and cone photoreceptor cells in the back of the retina.
01:24Vision
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.
01:20Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
01:15Depth Perception and Spatial Vision
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.
01:24Color Vision
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.
