The scientist finds the new born brain cell can remove old memory
November 14 according to medias of foreign countries news of scientific and technological news Beijing time of Sina, the Japanese scientist is here in 13 days>Publish and study the article and claim, the new born brain cell can destroy the connection between sea horse's brain cell of the district of brain on the magazine. The sea horse district is the area that a brain is involved in study and memory. The scientist says, removing old memory of the brain can be offered for studying new knowledge " The space " .
Disease Paul - Franko, neuroscientist of children's hospital in Toronto of Canada is blue to say, scientific research personnel put forward neuronal forming and remove old memory before this View,but Japanese scientist here>Article that magazine publish first to find evidence, prove research of view this. In the fifties last century, scientists found in the brain " L The sea horse district " Playing an essential role in the course of storing information, if excise the sea horse area, then the memory in the past will disappear together. The scientist has already known memory takes shape in the brain sea horse district at first, and then transfer to the other areas of brain and keep for a long time. Sea horse's body is mainly responsible for study and memory, the short-term memory in daily life is stored in sea horse's body, if one the intersection of memory and passage, for example one telephone number or one will transfer it to depositing into the cerebral cortex the intersection of what and sea horse's body that mention repeatedly within short time, become and remember permanently. During some time, memory exists in sea horse district and other areas of brain altogether. But whom scientist does not find out about yet, memory how remove from the intersection of sea horse and district after several months or several years? How does sea horse's nerve cell of the district fix information?
Japanese the intersection of Toyama and well head, neurologist of university, smoke colleague in he, utilize radiation and other genetic methods, prevent mouse's brain neuron from taking shape. These mice are put into special cage, they feel frightened to slight shocking by electricity in scientist's training. The scientist finds, these mice can only rely on the sea horse district to call frightened memory back. And compare with a group of mice, the neuronal forming of brain has not been blocked, they can " L Jumped over " The sea horse retrieves frightened memory while storing from brain minister one in the district. Scientific research personnel still find, through some sports of helping the neuron to form, what the district from the sea horse of the old memory of the mouse is removed accelerates. But well head smoke show result of study mean new born neuron it forms new memory to be unnecessary in in brain.
Scientific research personnel have also canvassed the neuron and formed the role in study and memory. The sea horse district is that the adult forms one of two neuronal new areas in the brain. Previous research shows, the new born neuron can strengthen " L The circuit of memory " . But the latest research of the Japanese scientist has overthrown this view, it is a connection between a brain cell of the old memory code in the district that the new neuron weakens even destroys the sea horse.
The well head is smoked and said : " Discovery of us deny neuron form important function in obtaining memory. The sea horse district neuron not only can remove old memory, can also obtain new memory while taking shape. " Speaking from the essence, the new neuron forms new memory by preventing sea horse district from being filled up with a large amount of old memory.
