Látórostokkal

Látórostokkal, often translated as "visual fibers" or "optic fibers," refers to the bundle of nerve fibers that transmit visual information from the retina to the brain. This crucial pathway is primarily composed of the axons of retinal ganglion cells. As these axons exit the back of the eye, they form the optic nerve. The optic nerve then travels through the optic canal and partially decussates at the optic chiasm, meaning that fibers from the nasal (inner) half of each retina cross over to the opposite side of the brain, while fibers from the temporal (outer) half remain on the same side.

After the optic chiasm, the visual information continues along the optic tracts. These tracts carry information from both visual fields to the lateral geniculate nucleus (LGN) of the thalamus, a relay station in the brain. From the LGN, further neurons transmit the visual signals via the optic radiations to the primary visual cortex (V1) located in the occipital lobe of the brain. Here, the initial processing of visual information, such as detecting edges and orientations, begins. The term "látórostokkal" thus encompasses this entire complex network responsible for our sense of sight. Damage to any part of this pathway can result in various visual impairments, ranging from blind spots to complete blindness.
