Summary
This review details the visual system, explaining how light stimuli are processed through parallel neural pathways from the retina to the brain. It covers neuronal functions and clinical impacts of visual cortex damage.
Area of Science:
- Neuroscience
- Ophthalmology
- Physiology
Background:
- The visual system processes light stimuli through complex neural pathways.
- Understanding these pathways is crucial for diagnosing visual impairments.
Purpose of the Study:
- To review the anatomy and physiology of the human visual system.
- To describe the parallel pathways involved in visual information processing.
- To correlate clinical syndromes with damage to specific visual cortical areas.
Main Methods:
- Review of existing literature on visual system anatomy and physiology.
- Analysis of neuronal functional properties in visual pathways.
- Description of multiple cortical processing areas and their roles.
Main Results:
- Visual stimuli are coded by multiple, separate, and parallel pathways.
- These pathways originate in the retina and extend to various cortical areas.
- Functional properties of neurons and cortical areas are detailed.
Conclusions:
- The visual system involves intricate parallel processing from retina to cortex.
- Understanding these pathways aids in comprehending visual perception and dysfunction.
- Clinical syndromes are linked to specific lesions within the visual cortical areas.

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.
01:24Overview of Anatomy and Physiology
Human anatomy is the scientific study of the body's structures. Some of these structures are very small and can only be observed and analyzed with the assistance of a microscope. Other larger structures can readily be seen, manipulated, measured, and weighed. The word "anatomy" comes from a Greek root that means "to cut apart." Human anatomy was first studied by observing the body's exterior and the wounds of soldiers and other injuries. Later, physicians were allowed to dissect the bodies of...
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...
01:26Visual System
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...
