What are brain hemispheres?
Like the larger brain, the brain has two hemispheres. The cerebellar hemispheres are located on both sides of a small area called vermis, which separates both hemispheres down in the middle. Each of the brain hemispheres is further divided into five lobes. Deep folds in the brain separate ten lobes. The cerebellum, located in the lower back of the brain, sits under the brain and behind the pons. This is different from the brain that has large surface folds that seem intricate. In fact, the cortex of the brain is one continuous layer of brain tissue firmly folded on top of each other. Although brain hemispheres represent only ten percent of the volume of brain, they contain more neurons than the rest of the brain. This is possible due to the firmly composed nature of the brain.eres are deep nuclei. All outgoing signals are sent through these cores. Cortex brain hemispheres evaluates incoming messages transmitting sensory and other data from the brain. Gentle fine -tuning is coordinated by this part of the brain because sensory messages are accepted and are sentSignals to the muscles. The brain damage causes lack of coordination and timing of movements and other problems, including speech problems.
Functionally, the brain is divided into three sections. Pontocerebellum consists of most cortex. Damage to this part of the brain is usually shown as a lack of coordination on the same side of the body as damage. Vestibulocerebell's injury or disease is characterized by dizziness and uncoordinated walking. If spinocerebellum is damaged by alcohol, injuries or diseases, walking walking becomes stunning and affected by posture.
several disorders affect the brain. Spinocerebellar ataxia is a degenerative genetic state characterized by progressive loss of coordination. More than ten different types of spinocerebellar ataxia are known depending on a specific gene mutation. Research revealed the connection between autism and decreased size of the cerebellar hemisphere. LimbEry and brain injuries also affect the functioning of the brain and result in a lack of movement control.
