| Google publishes the most detailed brain analysis |
Google and its partners from the Janelia Virginia Research Center released today the largest mental survey ever. The project includes the largest high-resolution brain map connected to all animals. Share a 3D model. This model can follow 20 million neuron synapses connected to 25,000 neurons in the Drosophila brain.
This model represents an important step in a complete communication map within the nervous system of the body, and this model uses detailed imaging techniques to map the path of the physical path of the brain, as it helps to link the physical part of the brain with specific neurological behaviors. to. The main objective.
This image is called neural contact and covers nearly a third of the Drosophila brain. The reason for choosing Drosophila is that it is so complex, but its brain is so small that it works compared to previous cases. Administration.
Unlike worms or other inferior animals, fruit flies have an integrated transfer system and advanced behavioral features such as dancing on flirtation, which makes them similar to humans, but much smaller.
The 3D map created by the Google FlyEM team and Janelia Center is a technological breakthrough, and it's the product of mechanic mechanics and hard work.
The first step in developing the map is to split each part of the Drosophila brain into 20 قطعةm pieces, about a third of the width of human hair, and then map the brain slices by dropping a stream. Electrons from the scanning electron microscope. ,
The data created contains about 50 trillion 3D pixels that are processed using algorithms to track the path of each cell. Although the Google account algorithm is very smart, there is still a lot of work to do to verify the work of the program.
According to Google, scientists at Ganelia Center spent two years and 100,000 hours validating a 3D map and path of each neuron using virtual reality glasses and custom 3D editing software, millions of neurons.
However, the created map covers only part of the Drosophila brain, which is referred to as the Hemi brain. The Drosophila brain contains 100,000 neurons, while the human brain contains about 86 billion neurons, indicating that we have more to build the human neuron network remotely.
The Google and FlyEM teams open the collected data to all open source users for viewing and downloading, and the team coordinates data, photos, videos and other information so that ordinary people can access it. Researchers around the world use it.
