Which lobe of the brain is responsible for seeing

Loss of sight is not always straightforward, however, and the person may instead lose one or more specific functions of their vision. Anton syndrome is a rare form of blindness that occurs without the person being aware of it.

They may deny their vision loss, even if a healthcare professional presents evidence showing that they have vision loss. Riddoch syndrome is a rare condition in which a person is only able to see moving objects. Stationary objects simply do not appear in their field of vision. The person can also not perceive shape or color. Epilepsy shares a link with the occipital lobe in some cases. If a person is more prone to occipital-type seizures or photosensitivity seizures, flashes of light or images that contain multiple colors may trigger these seizures.

The type of dysfunction to affect the body can vary based on where the dysfunction or injury occurs in the occipital lobe. Some possible examples include:. The occipital lobe is one of the four major lobes in the mammalian brain. The occipital lobe is mainly responsible for interpreting the visual world around the body, such as the shape, color, and location of an object.

It then relays this information to other parts of the brain, which give this visual information its meaning. Dysfunction in the occipital lobe may cause a number of bodily dysfunctions, such as irregular vision, difficulty standing, and blindness. Some conditions, such as epilepsy, may also have a link to dysfunction in the occipital lobe. The human brain is a hugely complex organ, made of different areas that handle different functions. The cerebellum is the part that handles many….

The central nervous system is made up of the brain and spinal cord. It gathers information from all over the body and coordinates activity. We explore…. Epilepsy is a fairly common neurological condition characterized by recurrent seizures. In this article, learn about the different types of epilepsy…. Epilepsy is a condition that causes seizures. It is relatively common in children. Learn about its causes, symptoms, and treatments here. The frontal lobe is a part of the brain that controls key functions relating to consciousness and communication, memory, attention, and other roles….

Everything you need to know about the occipital lobe. Medically reviewed by Seunggu Han, M. Although its primary role is to control vision, damage to other brain regions and body parts can inhibit vision. Moreover, some evidence suggests that, when the occipital lobe is damaged, nearby brain regions may be able to compensate for some of its functions. The occipital lobe is heavily dependent on:.

The most obvious effect of damage to the occipital lobe is blindness, but occipital lobe damage can have other surprising effects:. Spinal cord injuries are traumatic for patients and their families. They cause disruptive changes to every aspect of your life and there is a lot of new information to navigate and understand. Our experts have collected everything in one place to help you learn more about your injury, locate doctors and treatment centers, find financial support, and get assistance navigating your next move.

Author: Spinalcord. Where is the Occipital Lobe Located? What Does the Occipital Lobe Do? Those include: Mapping the visual world, which helps with both spatial reasoning and visual memory. Most vision involves some type of memory, since scanning the visual field requires you to recall that which you saw just a second ago. Determining color properties of the items in the visual field. Assessing distance, size, and depth. Identifying visual stimuli, particularly familiar faces and objects.

Transmitting visual information to other brain regions so that those brain lobes can encode memories, assign meaning, craft appropriate motor and linguistic responses, and continually respond to information from the surrounding world.

Receiving raw visual data from perceptual sensors in the eyes' retina. Those include: Brodmann area 17 : Known as V1, this region is located in the occipital lobe's calcarine sulcus, and serves as the brain's primary visual cortex. It aids the brain to determine location, spatial information, and color data. The ventral stream : Known sometimes as V2, this is a secondary visual cortex that helps the brain assign meaning to what it is seeing.

Without V2, you would still be able to see, but would have no conscious awareness of or understanding of the sights your eyes took in. The dorsomedial stream : Neuroscientists don't yet have a strong understanding of this brain region, which connects to both V1 and V2, as well as other brain regions. The lateral geniculate bodies : These structures take in optic information from retinal sensors in each eye, sending raw information to each visual cortex.

Lingula : this area receives information from the contralateral inferior retina to gather information about the field of vision. The occipital lobe is heavily dependent on: The eyes, particularly the retinas, which take in and process visual information to then be further processed by the occipital lobe.

The frontal lobe , which contains the brain's motor cortex. Without motor skills, the eyes cannot move or take in information from surrounding regions. The temporal lobe, which helps assign meaning to visual information, in addition to encoding it into memories.

What Happens if the Occipital Lobe is Damaged? The two hemispheres of the brain are each divided into four paired lobes: the frontal , the parietal , the temporal , and the occipital. See the diagrammatic representation below. Each lobe is responsible for different functions: the frontal for cognitive purposes and voluntary movement; the parietal for interpreting taste, movement, sensation touch , and taste; the temporal for memories and for integrating these with taste, sensation, sight and touch; the occipital for vision.

A hit to the back of the head, where the occipital lobe is situated can result in blurred vision as one of the possible symptoms. What lobe of the brain is responsible for vision? Suren Abreu. Jun 4, The occipital lobe.
