Structural sketch map of brain.

Exceed, recall the intersection of disease and man remember all thing to known as the human valley song all one's life
The Canadian scientist finds in surprise, place and stimulate the back of mound in the electrode of the human brain at the time of clinical research, unexpectedly help the brain to find passingly magically " Memory flows " ,Reappear like the cigarette past event. Researchers hope, further strengthen this kind of brain " pace maker " correctly Research,new route when repairing in order to lasting memory, be helped brain not to be kept by vigor, cure senile dementia.

Reducing weight retrieves the memory in surprise

This research is gone on by the west district hospital researchers of Toronto of Canada, the research report is published on " neurology yearbook " published on the 30th. The neurosurgeon of the west district hospital of Toronto firsts try and pursues to stimulate the brain through the electric current most, control the appetite for an obesity patient, but the result finds in surprise, the electric current stimulates patients to play the back of mound, help him to give a lot of memory parts for change, even let him remember the past event 30 years ago.

Group leaders of research group Andress and Lozano say, their discovery is " sheerly the accident " . It was a man 190 kilograms in weight that implemented electrodes and planted and started with the skill. Because all weight-reducing ways are inoperative to him, the doctor has to install electrodes in his brain, the ones that hope to stimulate producing the hungry sense, controlling appetite in the brain through the electric current are hypothalamic, help him to " eat few " . It has not influenced that the electrode stimulated the appetite to the patient finally, but made him remember a past event 30 years ago suddenly.

This man recalls, that section of memory is suddenly welled up like tidewater, he remembers oneself was probably more than 20 years old at that time, strolling in the park with the friends. The more magical one is, as current intensity is strengthened, the scene while remembering is more lifelike, the detail is more abundant, he sees that there is one's own girlfriend at that time among them, everybody was talking, it can be distinguished that even clothes worn are clear. And when the electric current is cut off, the memory is getting fuzzy and dull rapidly.

The electric current not only helps this man to find over, but also make his learning ability resumed greatly. In through three week continuously stimulate, test reveal he raise greatly to in pairs learning ability of object. In a situation that the electric current is put through, he is good comparing with the time when the electric current cuts off too to the learning ability of the object non- in pairs.

It is expected to cure senile dementia

After reaping and discovering in surprise, Canadian researchers set about to study amazing function on senile dementia of the deep brain. Researchers have implemented the experiment at first stage to 6 senile dementia patients. The hypothalamus that they gave to 3 patients is planted into the electrode, supply power in the battery of patient's chest and wire placed in the skull for it through sewing up. The current intensity of whole return circuit is very small, can stimulate directly in a situation that the human body has not perceived hypothalamically.

Researchers say, this research is of great significance, not only can let the scientist understand more, still can help people to improve the memory question.

" brain pace maker " It is extensive to employ

It is still for the first time " Set foot in " Senile dementia is studied, but the deep brain is amazing there are more than 10 years in clinical practice in the treatment, playing an important role in treating depression, chronic pain, parkinsonism and other movement functions not normal disease.

As the amazing domain expert of deep brain, Lozano has already implemented electrodes and planted and started with the skill for more than 400 parkinsonism patients and 28 depression patients. He says, this kind of treatment is very effective for treating the question of moving of muscle caused by parkinsonism, have already been adopted by more than 40,000 patients so far. With the development of science and technology, a whole set of brain " pace maker " The device volume will become smaller, the operation risk will be greatly reduced, the erection site is more accurate too.

Chaining

Hypothalamic daily function

The hypothalamic position does not usually think that have relations with memory. It is usually considered to regulate the advanced centre that the viscera move about that hypothalamic, it is the advanced centre of regulating the endocrine too. Some hypothalamic cells are the neuron, and endocrine cells. In the organism, mainly depend on being hypothalamic to the regulation of body temperature, ingesting, horizontal weighing apparatus, endocrine,etc., it participates in the emotional responess activity too at the same time.
