In this age of pretentious genius, if you ask us who is the smartest person in the world? I believe that Einstein's cute and serious face will still flash in the minds of most men, women and children.
Einstein died on April 18, 1955, of a ruptured aortic aneurysm at Princeton University Hospital in New Jersey, but his brain has been preserved to this day. Some of the genius's brain tissue slices are on display at the Mutter Museum and the Wellcome Collection in London, England. Many medical researchers and the public are scrambling to see the brain of this great man. In addition to the curiosity about the genius brain, people have also begun to pay attention to the physiological function and operation mode of the brain.
The brain is one of the most amazing organs in the human body. Through the brain's highest regulation, people can make specific responses to their external environment, can imagine complex worlds, and can make plans and set goals. The human brain weighs about 1.4 kg. In a second, each neuron in the brain can emit up to 1,000 faint electrical signals (less than one-tenth the voltage of a No. 1 battery) that travel between neurons at lightning speeds of up to 400 km/h. The number of connections between neurons in the brain can exceed 100 trillion, and the proper functioning of the brain depends on these complex connections. Aside from the way it works and the way it works, the way it works is amazing. Previous studies have shown that taxi drivers need to memorize many road signs and streets in their daily work, so the hippocampus area responsible for long-term memory storage and retrieval is significantly larger than that of ordinary people.
However, such a display of the brain can leave you drowsy, and a curious museum of the human brain is born. Unlike other museums, much of the Collection of the Museum of the Human Brain comes from years of collections by medical workers. Therefore, the smell of formalin inevitably lingers in the museum. Before entering the museum, one must be brave enough to appreciate these treasures.
< h1 class= "pgc-h-arrow-right" > the Peruvian Brain Museum in the "Burrow"</h1>
The world's largest open museum of the human brain is located in Lima, the capital of Peru. It is funded by the National Institute of Neuroscience of Peru. In this humble little room, there are more than 3,000 brain specimens, of which the brains of patients who died of mad cow disease are the most popular among tourists. The museum's director is neuropathologist Diana Rivas.
Rivas said the Peruvian Neurological Institute has been collecting the brains of dead patients for scientific research since 1947. After fifty or sixty years of accumulation, there are now so many brain samples. The museum's exhibits include brain specimens from patients who died of cancer, Alzheimer's disease, heart failure and mad cow disease. At the same time, due to the high number of deaths from trichinellosis in Peru, samples of the brains of such deaths are also included in the exhibits.
In addition to the diseased brain, there are also brain specimens of abnormal fetuses. At the same time, there is also an autopsy room, and Rivas performs more than 100 autopsies a year, making it easier for her to put new specimens on shelves for public viewing. The museum is also known as one of the must-visit places for medical staff. Every year, scholars from all over the world come here to visit and study. Rivas said that her greatest pleasure is to introduce visitors to various brain diseases, hoping that visitors will cherish and care about their own and others' health after visiting. Museum commentary only needs to be booked in advance, and the adult admission ticket only needs 1 Peruvian nuevo Sol (equivalent to RMB 2), which is definitely worth the money.
<h1 class= "pgc-h-arrow-right" > "horror" of the Japanese Brain Collection</h1>
In addition to medical workers who are interested in the human brain, there are also ordinary people who have a strong curiosity about the human brain. Japan has a unique private private celebrity brain collection. If it takes courage to visit the Museum of the Human Brain in Lima, Peru, then it takes 200% courage to visit this Folk Brain Museum, because before entering the exhibition hall, you must first watch a horror movie. If you think that if you stick with watching horror movies and then you can enjoy the exhibits, you're wrong. The journey of horror has only just begun. With an uneasy heart, visitors will be taken to another grim and frightening situation – the dissection laboratory. As soon as you enter the lab, you will feel the taste of formalin. The layout has the characteristics of a Japanese horror film: the dissected brain is placed on the workbench, in front of which are the skin of stumps, severed arms and tattoos, and in the back is the formalin corpse pool. This strong shock from the sense of sight and smell is no less challenging to the heart than a crazy roller coaster! Curator Sato said that there used to be a girl who was afraid of fainting and ended up with schizophrenia sequelae, so people working in this collection must be bold and have a master's degree or above. Currently, most of the men in this museum are working.
The museum was built in 1913 and mainly collects and studies the brains of celebrities. Over the past 100 years, the brains of 181 celebrities have been collected, including the brains of several Japanese politicians such as Katsura Taro, Takeo Miki, Kakuei Tanaka, and Keizo Obuchi, as well as the brains of modern Japanese celebrities, scientists, and artists. The purpose of the museum is to explore the evolution of the human brain and study the similarities and differences between different races, genders and groups of different levels of intelligence.
Currently, researchers at the museum have compared the anatomy of male and female brains and found that the brains are naturally divided into sexes. For example, only the left brain of men has yellow-brown or reddish-brown spots that regulate language function, while women have such spots on both sides of the brain. Therefore, women are more gifted in language than men.
In addition, the results show that the average brain weight of yellow, black, and white people is almost the same, which overturns the erroneous assertion that whites are inherently smarter than yellows and blacks. Library research also shows that the brains of great people are usually heavier than those of ordinary people. Einstein's brain was long and large, with a mass of 1680 grams. The average weight of the Japanese brain is 1300 grams. The heaviest brain of a Japanese celebrity in the museum can reach 1645 grams. At the same time, they also found that many criminals have heavier brains than the average person. The researchers believe that the brains of these gangsters may also have some special abilities, but they are not properly utilized and develop into distortions. But the relationship between brain mass and human intelligence is not absolute.
<h1 class="pgc-h-arrow-right" > a human brain theme exhibition for the general public</h1>
In addition to the dedicated Museum of the Human Brain, many comprehensive large museums in the world have also begun to hold exhibitions on the theme of the human brain. Once, the Natural History Museum in New York hosted an exhibition called "The Mystery of the Brain." The exhibition covers the evolutionary history, organizational structure and functioning of the brain, and how the brain coordinates senses, processes emotions, and thinks.
With the help of the latest research results and exhibition technology, through imaginative works of art and vivid brain scan images, visitors can more intuitively and vividly understand the evolution of the brain over millions of years, as well as the activity of molecular, chemical and electrical signals in the brain, the realization of advanced cognitive functions of the brain, and the development of brain plasticity. The exhibition is neither very professional nor scary, so it is suitable for visitors of all ages. Through the exhibition, visitors will be in awe of the brain, from the exhibition content to understand the brain's structure, chemistry, evolution and development process, exhibition planner and geneticist Robert Sal said, some new technologies to treat Alzheimer's and Parkinson's disease are also on display.
Doctors can implant electrodes into a patient's brain through brain surgery and use microcurrent stimulation to regulate the activity of nerve cells in the brain. So far, more than 80,000 people with Parkinson's disease have undergone this deep brain electrode implantation. At the same time, the exhibition also raises ethical questions, such as whether such treatments can be used to improve memory in healthy people.
