Occipital lobes are responsible basically for visual processing and are the center of visual perception system. They are not very much vulnerable to injuries due to their location at the back of the brain, but nevertheless any injury can produce changes to the visual-perception system. When one side of occipital lobe is damaged it can result in homonomous vision loss with the same field cut in both eyes.
Disorders of this lobe can also cause visual illusions and hallucinations. Visual illusions appear in the form of distorted objects and abnormal coloring of those. Visual hallucinations, when there are no external stimuli for such an image, appear after temporal lobe seizures or lesions to occipital part. Word blindness is another problem with occipital lobe injury; the person just becomes unable to recognize words. The person with occipital lobe problems is also unable to recognize movements of the objects, which is called movement agnosia, and also have difficulties with reading and writing.
The patient can even loose sight or obtain what is called cortical blindness, when the person has normal eyes, reflexes and eye movements, but lacks the perception pattern and has no idea of visual information.
Temporal lobe is responsible for perception and recognition of auditory stimuli. It has two essential sulci running parallel Sylvian fissure, and they separate temporal lobe into three gyri: This lobe type is very important for language, especially in managing lexical and semantic information. There are eight main symptoms of the temporal lobe damage, which include disturbance of selective attention of auditory, of visual input, auditory sensation and perception, disorders of visual perception, impaired organization and categorization of verbal material, as well as long-term memory, altered personality and affective behavior, as well as altered sexual behavior, and finally disturbance of language comprehension Kolb and Wishaw, Damage of temporal lobes leads to selective attention to visual or auditory input.
When the left side of the lobe is injured it results in decreased recall of visual and verbal content. When the right side is damaged, it results in tonal sequences decreased recognition and decrease in musical abilities.
Temporal lobes are in the sensory input primary organization. Temporal lobe seizures can also have serious effects on the personality of the individual. In the conclusion I would like to summarize that there are four structural divisions of the brain- frontal, parietal, occipital and temporal.
They all perform their functions, even though sometimes those functions are interrelated. Thus, it can be concluded that human brain is a very complex organ which is responsible for multitude functions, and an unknown number of those functions is not yet known. There is still ongoing research on the composition and functions of brain. Each of the parts of the brain is responsible for some essential function without which the body will not be able to function normally.
This attribute makes the brain the most essential part of the human body.
