Four Major Surfaces Of The Brain

The Brain is said to be the center of the nervous system of the human being. Brain consists of four main structural divisions or lobes. They are: frontal, parietal, occipital and temporal. All lobes carry particular function and dysfunction of any can bring the person serious troubles.I will describe four lobes of the brain, as well as identify how these lobes relate to psychological functions.

Frontal Lobes
Frontal lobes are responsible for reasoning, planning, movements, emotions, parts of speech and problem solving functions. Frontal lobes are the center of the emotional control and the shelter of our personality. It is the only part of the brain where lesions are capable of causing a wide range of different symptoms. The frontal lobes are involved in memory, spontaneity, initiation, language impulse control, motor functions, as well as sexual and social behavior. These lobes are very vulnerable to injury because of their location at the cranium front. They are also situated in proximity to sphenoid wing.

Parietal Lobes
Parietal lobes are responsible for orientation, recognition, stimuli perception and movement. They can be divided into two functional
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. Occipital lobe’s peristriate region is involved in visuospacial processing, movement and color discrimination. When one side of occipital lobe is damaged it can result in homonymous 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
