Occipital Lobes-
The Occipital Lobe is the posterior lobe of each cerebral hemisphere having the shape of a three sided pyramid and containing the visual center of the brain.The occipital lobes are the center of our visual perception system. They are not particularly vulnerable to injury because of their location at the back of the brain, although any significant trauma to the brain could produce subtle changes to our visual-perceptual system, such as visual field defects and scotomas.The Peristriate region of the occipital lobe is involved in visuospatial processing, discrimination of movement and color discrimination
What are some of the problems that can happen if there is damage done to the Occipital lobe?:
Damage to one side of the occipital lobe causes homonomous loss of vision with exactly the same "field cut" in both eyes. Disorders of the occipital lobe can cause visual hallucinations and illusions. Visual hallucinations (visual images with no external stimuli) can be caused by lesions to the occipital region or temporal lobe seizures. Visual illusions (distorted perceptions) can take the form of objects appearing larger or smaller than they actually are, objects lacking color or objects having abnormal coloring. Lesions in the parietal-temporal-occipital association area can cause word blindness with writing impairments.
