As visual information exits the occipital lobe, and as sound leaves the phonological network, it follows two main pathways, or "streams". The ventral stream (also known as the "what pathway") leads to the temporal lobe, which is involved with object and visual identification and recognition .
The visual system is the physiological basis of visual perception (the ability to detect and process light).The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment.
Recent descriptions of visual association cortex describe a division into two functional pathways, a ventral and a dorsal pathway. This conjecture is known as the two streams hypothesis . The human visual system is generally believed to be sensitive to visible light in the range of wavelengths between 370 and 730 nanometers of the ...
Full redraw: Group labels in accordance with the "Foundational Model Explorer." Added "Macula" and "Uvea" and removed "Zonular fibres." It has given better visibility inside the eye. The eyeball shape and size of different parts of the eye are now real...
It is composed of two individual tracts, the left optic tract and the right optic tract, each of which conveys visual information exclusive to its respective contralateral half of the visual field. Each of these tracts is derived from a combination of temporal and nasal retinal fibers from each eye that corresponds to one half of the visual ...

The tectopulvinar pathway is a fast-acting pathway that provides the viewer with information on the absolute spatial information of objects. The pathway plays a large role in directing visual spatial attention and is particularly responsive to novel stimuli that appear or move in peripheral vision; however, because it receives mostly magnocellular visual input, the tectopulvinar pathway is not ...
The visual pathway consists of structures that carry visual information from the retina to the brain.Lesions in that pathway cause a variety of visual field defects. In the visual system of human eye, the visual information processed by retinal photoreceptor cells travel in the following way:
