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 · Structure and Function. 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.
We will dive deeper into the higher-order processing visual pathways, the dorsal and ventral streams, to better understand how our brain recognizes and interprets our visual world and what happens if these visual pathways are damaged or interrupted.
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).
Before learning the pathway that visual information takes from the retina to the cortex, it is necessary to understand how the retina views the world around us. The full visual field includes everything we can see without moving our head or eyes.
Key Takeaways. Test Yourself. In this chapter we will learn about how the information from the retina is processed centrally within the brain. Visual Fields. Before learning the pathway that visual information takes from the retina to the cortex, it is necessary to understand how the retina views the world around us.
