A man who is stuck in the 1950s

Amazing case of violation pamyati

Henry Gustav Molison been under medical supervision since 1957, the year before his death in the year 2008. From an early age he suffered from a severe form of epilepsy, the cause of which, perhaps, was the fall from a bicycle at age seven.



He constantly had a seizure, as they grow older is becoming worse, finally, the attacks have become so strong that Molison fainted. Work he could not, he had to move in with her parents. In 1953, when he was 27 years old, Molison got to the neurosurgeon William Beecher Scoville from Hartford Hospital in Connecticut.

After a simple treatment yielded nothing, Scoville offered to do experimental surgery - to remove Molisonu part of the brain to reduce seizures. Desperate patients agreed and in August 1953, the operation was carried out: it involves the removal of most of the parts of the hippocampus and temporal lobes - Scoville thought in causing seizures blame these areas.

During the procedure Molison was conscious, he made only a local anesthetic. At first glance, everything was going well, but later Scoville acknowledged that the operation was "a tragic error". However, this error has become extremely important for neuroscience.

Seizures really stopped, but the operation is strangely influenced Molisona memory. He could recall the events of the distant past, but does not remember anything from recent events or new facts - memories held no more than 20 seconds, and then Molison forget everything. He also did not remember anything of what happened a year or two before surgery, and he had memory lapses concerning the events of the past 11 years.





Molisonu managed to master some new motor skills: play a musical instrument, or the ability to play in a modern computer game. When asked to repeat these steps, he did not remember that he ever studied, but repeated easily. Also, he was able to remember little information about public life, such as the names of some celebrities.

At the time of surgery, most scientists believed that memory is distributed throughout the brain and is not associated with any one area. Molison demonstrated that there are various types of non-volatile memory, depending on the different regions of the brain.





Memory loss is not given Molisonu move forward in life. In 2004, he still thought that the US president is Eisenhower, and he himself - a dark-haired man of middle age, it was in the 1950s. Work he could not have lived with his parents, but he was able to perform household chores like going to the store or work at home - he remembered how to do them. Molison died in a nursing home in 2008 at the age of 82 years. He bequeathed his body to science, and after his death, scientists have continued to study his brain.
