	Evolution of the Avian Visual System
		Such similarities include: the importance of the tectum as a visual structure for maintaining topographic representation of sensory space, and the possession of dorsal thalamic zones in both birds and mammals which receive ascending visual input from the retina either directly (lemnothalamic pathways) or indirectly (via the tectum, as in the collothalamic pathways).
		Visual processing beyond the retina is discussed with comparisons between the collo- and lemno-thalamic visual pathways in amniote brains.
		From the pineal eyespot under the skin of amphibians to capabilities of the primate eye, the evolution of visual functions are driven by the content of the photic stimulus (i.e., wave and particle properties of light) and the physical and biochemical constraints of living organisms.

	Visual system - Wikipedia, the free encyclopedia
		The visual system is the part of the nervous system which allows organisms to see.
		The neurons of the LGN then relay the visual image to the primary visual cortex (V1) which is located at the back of the brain (caudal end) in the occipital lobe in and close to the calcarine sulcus.
		The visual cortex is the most massive system in the human brain and is responsible for higher-level processing of the visual image.

	Webvision: Visual Cortex
		The human visual system can detect and discriminate between an incredibly diverse assortment of stimuli that may be chromatic or achromatic, in motion or not, pattered or unpatterned, two-dimensional or three.
		Visual input to the brain goes from eye to LGN and then to primary visual cortex, or area V1, which is located in the posterior of the occipital lobe.

	The Visual System and Childhood Brain Tumor
		Warning signs in the visual system would be unexplained visual loss, jiggling or nystagmus of the eyes, exotropia (an outward deviation of one eye), and amblyopia that does not improve with conventional therapy.
		The ocular motor system is a complex interconnection between the brainstem (pons and midbrain) which is responsible for the final control commands for eye position and nearly every other part of the brain which is responsible for producing or modulating those commands to the eye movement centers.
		The visual system of children under the age of 8 years is still developing and abnormal visual input when the eyes are not aligned properly may lead to a permanent impairment, known as amblyopia.

	Visual Prolog Object System
		The class based object system in Visual Prolog is based on the idea of separating class declarations from their implementation, so that class declarations can be used as "contracts" between the implementation and the usage of the class.
		In Visual Prolog this problem is not a problem, the type representing our specific tribe can be a subtype of the type of persons from any tribe, and the classes implementing people from any tribe can inherit from the class implementing persons from our specific type.
		The object system is based on the ideas of C++, but it tries to overcome some of its problems by applying modern ideas and to be less "compiler pragmatic" and focus more on programmer pragmatics.

	Central Visual Pathways
		This highway of visual information courses through the white matter of the temporal and parietal lobes, and can be very vulnerable to strokes.
		In the end, the parietal visual cortical areas (such as MT and PP) end up dealing with motion of objects, navigation through the world, and spatial reasoning (which is essentially moving things around in your head).
		Temporal visual areas (such as V4 and IT) are involved with the complex perception of patterns and forms as recognizable objects.

	The visual\|catalogues System
		a shareware system for generating catalogs or brochures of visual information off-line and using these in-house or across your local network, or publishing these on-line to the Internet for access from public web pages, for displaying on an Intranet, or for distributing free or for sale on CD-Rom or CD business card.
		The system is visual in that it displays thumbnail images of items which provide at-a-click access to more detailed visual representations, such as larger images, movies, textual documentation, or to the many other types of representations and file types that can added as part of each cataloged item's record.
		The system can be set up to allow users to search across single or multiple catalogs from one interface, either on-line or from network or CD Rom.

	Transducer: Digital Audio-Visual Performance System
		The most notable aspect of this approach is the sense of comprehensibility that the system appears to have, in spite of its gesture complexity.
		Thus any interactive system that emphasizes the process of action or the event of interaction may be thought of as a "digital performance," though it may only have an audience of one.
		Since our interface to the system is primarily gestural and our primary focus is on the ability to immediately conceptualize expression, we are not concerned with the precise representation of sound or visual structure.

	HHMI News: A New View of Visual System Development
		These neurons are grouped in the visual cortex in patches called orientation columns, with those responding to a given type of stimulus occupying the same column.
		Researchers have shown conclusively that visual experience in early life is essential for the visual cortex to function properly.
		A series of experiments showed that this communication occurs via a feedback loop between the visual cortex and the thalamus, the part of the brain in which the LGN is located.

	About the Visual Catalogues System
		Note that the system is structured so that it can be linked to other SQL databases if required, for example to MS SQL Server* for very large or existing databases.
		The system keeps a track of what you have uploaded to your site, and by default on update only copies over those entries that have been added or changed.
		Building keyword searches using the system, generates a flat file database that is used by both the Windows viewing interface, and the Java applet viewer.

	Center for the Study of Autism
		This is a case of rivalry between the two visual systems; they are competing and out of synch.
		If one is using just his/her identification portion of the visual system, he/she will likely take a long time to process the information so it will be difficult to attend while they are thinking.
		When the visual system is dysfunctional, an individual holds his/her toes longer to the ground; and the body moves with the appearance of the toe turning in.

	The Visual Pathway
		Signals produced by rod and cone cells in the retina then start on their way into the brain through the optic nerve and reach a major relay station, the LGN (lateral geniculate nucleus).
		Signals about particular elements of the pencil then travel to selected areas of the primary visual cortex, or V1, which curves around a deep fissure at the back of the brain.
		From there, signals fan out to "higher" areas of cortex that process more global aspects of the pencil such as its shape, color, or motion.

		• Our visual system is sensitive to a portion of the electromagnetic spectrum (in wavelength, the typical way of talking about light waves, from a bit less than 400 nm to a bit more than 700 nm).
		Because the cornea's refractive power remains stable while the refractive power of the lens decreases, as one ages the proportion of light bent by the cornea becomes an increasingly large proportion of the total light-bending capability of the eye.

	Writing an AJAX-based Visual Rating System with PHP — a/r/t by php\|architect
		AJAX allows you to provide a very intuitive interface that doesn't require the use of forms—therefore, there is never any wasted page real estate, since the same visual controls are used to cast a vote and to display the current rating.
		We want our rating system to be visual—providing the user with a means of both determining the average rating of a web page and casting his or her own vote using the mouse.
		The easiest way to do so is to create an image that visually represents the rating like the one shown here on the top-right; a user can click on this image to indicate his or her own vote—the further right he or she clicks, the higher the vote.
