The frontal lobe up front, the parietal lobe on top, the temporal lobe on bottom and the occipital lobe pulling up the rear. All of our senses, thoughts and actions start in one of these lobes. Most visual functions are controlled in the occipital lobe, a small section of the brain near the back of the skull.
Where does vision take place in the brain?
From the thalamus, visual input travels to the visual cortex, located at the rear of our brains. The visual cortex is one of the most-studied parts of the mammalian brain, and it is here that the elementary building blocks of our vision – detection of contrast, colour and movement – are combined to produce our rich and complete visual perception.
How does the brain process vision?
Vision requires distilling foreground from background, recognizing objects presented in a wide range of orientations, and accurately interpreting spatial cues. The neural mechanisms of visual perception offer rich insight into how the brain handles such computationally complex situations.
The tiny nerve cells are able to take the electric form of the image in front of you and send it to the brain’s visual cortex or “Vision Center.” The “Vision Center,” is located in the back part of your brain (the occipital cortex or lobe). It is responsible for decoding the electrical information coming from the retina.
Well, as the visual input works its way up the hierarchy, these simple features are combined to create more complex features, until at the top of the hierarchy, neurons can represent complete visual objects such as a face. This bottom-to-top processing of our visual world may seem the logical path, but it isn’t the whole story.
What part of the brain is responsible for vision?
The “Vision Center,” is located in the back part of your brain (the occipital cortex or lobe). It is responsible for decoding the electrical information coming from the retina. The vision center interprets the electric form of the image, allowing you to form a visual map. As you can SEE, vision is a complex process.
This of course begs the question “Where is the visual cortex located in the brain?”
Visual information from the retina is relayed through the lateral geniculate nucleus of the thalamus to the primary visual cortex — a thin sheet of tissue (less than one-tenth of an inch thick), a bit larger than a half-dollar, which is located in the occipital lobe in the back of the brain .
What part of the brain controls eyesight?
Most visual functions are controlled in the occipital lobe, a small section of the brain near the back of the skull. But processing eyesight is no simple task, so other parts of the brain have to pitch in too. The occipital lobe is solely responsible for observing and processing the raw image “data” sent from the outside world through the eyes.
What part of the brain does the optic nerve end?
The optic nerve ends in an area of the brain called the lateral geniculate nucleus, which is located in the thalamus, a structure located close to the center of the brain. The information is then sent from the lateral geniculate nucleus to the primary visual cortex, which is located in the occipital lobe,.
The optic nerve primarily routes information via the thalamus to the cerebral cortex, where visual perception occurs, but the nerve also carries information required for the mechanics of vision to two sites in the brainstem. The first of these sites is a group of cells (a nucleus) called the pretectum,.
