Answer:
Step-by-step explanation:
The retina, which is the light-sensitive tissue lining the inner surface of the eye, contains photoreceptor cells that convert light signals into electrical signals, which are then transmitted to the brain through the optic nerve. These signals are processed in various regions of the brain, including the visual cortex, where the brain interprets the electrical signals into visual information.
In terms of the visual pathway, the optic nerve carries these signals from the retina to the brain. The optic nerve fibers from both eyes come together at a point called the optic chiasm. From the optic chiasm, the fibers split and project to different parts of the brain. Some fibers continue to the lateral geniculate nucleus (LGN) of the thalamus, and from there, they project to the primary visual cortex, which is located in the occipital lobe of the cerebral cortex.
The primary visual cortex is the part of the cerebral cortex responsible for initial processing of visual information. It's where the brain begins to make sense of the electrical signals sent from the retina. The visual information is then further processed in different areas of the cortex, allowing us to perceive and interpret the visual world around us.
In summary, the retina extends its neural signals through the optic nerve to different parts of the brain, ultimately reaching the primary visual cortex in the occipital lobe, where visual information is processed and interpreted.
