Half of the entire brain, okay?




This 1888 ? Was in , German doctors frydrc guyz through the operation of a dog thrown out half a brain . He wanted to see what kind of animal from the psychological and physical changes are born . A few months later, the dog was recovered , the doctor was surprised to learn that frydrc the dog's mental abilities that made ​​no difference , just the upper half of the body part was useless . The world's first operation in which half of the visceral brain was removed . The operation of medical " term cohesion Hemisphere " (Hemispherectomy) is called .
Neurosurgery father in 1923 , the first American doctor ultr Hugh connection Hemisphere operation . A patient suffering from a brain tumor removed half a brain . The patient lived for three years and then put an end to this cancer . Since this operation is performed on specific patients . But it is one of the most difficult and complex operations .
A side effect of Hemisphere connection seen in 1938 . When Canadian neurosurgeons , Kenneth Mackenzie kabzryah a sixteen year old girl drove half a brain operation . She was suffering from epilepsy . When he was healthy , so amazing at it when I ran out of epilepsy .

Today, these men and women is of special operations who had daily seizures of epilepsy , they have no effective drug and disease of the brain hemisphere ( half portion) are centered . Actually, this medical condition is not controlled , then it affects the whole brain . That's why half the brain is removed affected by the operation . There are two types of connections Hemisphere operations , anatumykl and Functional !
In the latter half the brain is removed. Half of the functional parts of the brain and corpus kalusm (Corpus callosum) are extracted . The brain that connects the two parts together kalusm corpus .
American John hupknz anatumykl operations are performed in the hospital . This operation is necessary because half the brain out to be a minor part , then come back Epilepsy .
America 's hospitals , UC LA are mostly functional operation . Feature of this operation is that the blood loss is reduced . These operations are typically 1 to 10 year olds .
The amazing thing is that after the operation the patient is a child's mental growth is normal . End of epilepsy is particularly painful disease , which is great . Moreover , many children then get rid of the disease fared significantly . Became a U.S. state chess champion . The second was the best bowler in your school . The remaining patients are children academically excellent work .
Although this operation has negative effects . In this context, John hupknz hospital neurosurgeons , Jon Freeman says " the operation rather athletic person can walk . But an arm of the patient is rendered useless . Also taken in the direction of the brain that is also eye- sight . "
In the past it was considered a child after the age of two years rent cohesion Hemisphere operations , he has difficulty in speaking . But John hupknz operations in this theory was revoked . Revealed that the operation was running five six -year-old child speak . However, it must be in operation early enough , the child will be affected , the lower the power of speech .
Connection Hemisphere operations , told the first person mind is the most powerful organ . Half of it will even excluded , even quite a few ways a man can live . But to get rid of severe disease , such as epilepsy .
Scientists do not yet understand what changes in the brain that half are born from the man lifts the burden of all mental tasks . Now he rysunyns functional magnetic imaging ( machine) to learn the mysteries are attempted . To know the process of the human brain 's flexibility and ability to change can know a lot about .
But this operation brings man to get rid of the chickens . Still, many parents think that their children try it on one arm and one eye will be disabled . Even if they make life miserable for epilepsy , so this operation is inevitable .
