What happens when the occipital lobe damaged?

Answer 1

1) disturbance of auditory sensation and perception,

2) disturbance of selective attention of auditory and visual input,

3) disorders of visual perception,

4) impaired organization and categorization of verbal material,

5) disturbance of language comprehension,

6) impaired long-term memory,

7) altered personality and affective behavior,

8) altered sexual behavior.

Answer 2

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 (Westmoreland et al., 1994). 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 (alexia and agraphia) (Kandel, Schwartz & Jessell, 1991).

Answer 3

According to Kolb & Wishaw (1990)
There are eight principle symptoms of temporal lobe damage:
1) disturbance of auditory sensation and perception,

2) disturbance of selective attention of auditory and visual input,

3) disorders of visual perception,

4) impaired organization and categorization of verbal material,

5) disturbance of language comprehension,

6) impaired long-term memory,

7) altered personality and affective behavior,

8) altered sexual behavior.

Answer 4

Damage to the occipital lobe can cause visual disturbances such as difficulty recognizing objects, impaired depth perception, and loss of ability to distinguish colors. It can also lead to vision loss, hallucinations, and problems with visual processing and perception.

Answer 5

As the occipital lobe contains our primary vision center if that area of the brain were damaged, we would most likely suffer some type of vision damage up to blindness.

Answer 6

loss of consciousness
