The Puzzle of Visual Development: Behavior and Neural Limits
1Center for Neural Science, New York University, New York, New York 10003 lk6@nyu.edu.
Summary
Visual development in infants shows poor sensitivity at birth, improving over time. Research into amblyopia, a vision disorder, highlights the brain
Area of Science:
- Neuroscience
- Developmental Biology
- Ophthalmology
Background:
- Infant visual function develops slowly, with poor initial sensitivity.
- Neural mechanisms of visual development are poorly understood.
- Early visual development exhibits significant brain plasticity.
Purpose of the Study:
- To review research on visual development and amblyopia.
- To explore the mismatch between visual cortex and behavior.
- To consider potential resolutions for visual processing deficits.
Main Methods:
- Historical perspective on visual development research.
- Analysis of neural organization and receptive field properties.
- Discussion of visual plasticity and sensitive periods.
Main Results:
- Infant visual systems show mature neural organization despite poor function.
- Abnormal visual experience during sensitive periods can cause amblyopia.
- Extrastriate visual areas may limit function and be vulnerable.
Conclusions:
- The primary visual cortex may not fully explain visual behavior limitations.
- Further along visual pathways, extrastriate areas are implicated in visual deficits.
- Multiunit activity analysis may reveal information flow to higher visual areas.

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

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.

The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...

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.
