Thanks to the mouse that saw the pieces of ‘Matrix’Among other audiovisual jewelry, scientists have created The largest functional map of the brain To date: up to 84,000 neurons, a section neurological map publishes messages between them. From a portion of this Cinefyl rodent brain, the size of a poppy seed, researchers have identified these neurons and how they communicate 500 million unions or sync.
Great data collection published on Wednesday by ‘Nature’ is a step to unravel The mystery of our brain. Data, a Color 3D Reconstruction Define different brain circuits, They are open Scientists around the world, or simple men can notice to create additional research.
“This is definitely a sense of surprise and the images of galaxies,” he says Forrest ColemanOne of the main researchers of the project is Allen Institute of Cerebral Science in the United States. “With the beauty and complexity that can be seen in these neurons and hundreds of millions of connections between them, it becomes an idea of how complicated it is (…).”
The way we think, feel, see, speak and move is due to how brain neurons and messages are implemented and sent. Scientists have long been aware that these symptoms move with fibers from one neuron to another Molds and tendrightsUsing Sinapsus to go to the next.
But less about neurons that perform some tasks, or how Those wiring changes may play a role AlcellusAutism or other disorders. Through this new scheme, the international group of more than 150 researchers has mapped neurological attachments, compared to the complex cheerful pieces that throws over the brain of Colman rodents.
How have scientists noticed the brain of rats?
The first step is to show a mouse Science fiction movies piecesGame, animation and nature. It used the mouse that was altered with a gene by a group of Baylor Medical College (USA) It makes their neurons shine When they are active.
Researchers used laser microscope to register How to blink the animals’ visual lining cells while processing images. Next, scientists of Alan Institute use a special tool using a special tool and take nearly 100 million high -efficiency images with electronic microscopes. Then, 3D data is fully assembled.
Finally, scientists at the University of Princeton (USA) used artificial intelligence (AI), and we can find all that wiring and “can identify each cable of different color separately.” Experts calculate it Microscopic wiring, if it is drawn, is 5 km..
What impacts have on humanity on this research?
So,Can this type of map can? Help scientists to find treatments for brain diseases? Researchers consider this According to the start As it happened with the Human Genetic Program, it provided the first gene maps and treatments based on genes.
One of the next objectives Cartography is a complete brain of a mouse. “The technologies developed by this project will give you the first opportunity to actually identify some type of irregular connection that leads to a disorder,” says Princeton’s neurologist, computer scientist and key researchers of the project, Sebastian Chiung.
Work ”considers that A great step It provides an precious social resource for future innovations, “Harvardin’s neurologist, Mariela Petkova and Gregor Shuhkanech, who do not participate in the project. They conclude that they will help to unravel the complex neurological networks that have been shared by the public.”
