27 lip 2023 · The visual pathway refers to the anatomical structures responsible for the conversion of light energy into electrical action potentials that can be interpreted by the brain. It begins at the retina and terminates at the primary visual cortex (with several intercortical tracts).

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.
19 gru 2022 · The visual system consists of 2 primary parallel pathways: optic and pupillary reflex pathways. [2] [3] Optic Pathway. The optic pathway begins in the retina, a complex structure of 10 layers, each serving a distinct function.
The visual system has to perform three basic functions: first, to see an object clearly; second, to identify it; and finally, to track it. These roles are carried out by different parts of the visual pathway (Fig. 7.3).
1 kwi 2017 · Vision is the primary sense in humans. There are approximately one million axons in the optic nerve, constituting almost 40% of the total number of axons in all cranial nerves. The primary sensors...
The visual pathway. Our direct biological response to light is primarily through the visual system. This includes image processing and refractive state along with awareness of day and night. The visual pathway is divided into the ventral and dorsal streams for both detailed perception and direction of action.
2 maj 2017 · The visual pathway is composed of four neuronal elements. Photoreceptors, bipolar cells, and retinal ganglion cells are found in the retina. Axons of ganglion cells pass through the optic nerve, optic chiasm, and optic tract.
