Brain diagram in the style of rainbow colors

US scientists publish the first complex diagram of the mammalian brain.

Recently, the Allen Institute of Brain Research Science in Seattle (USA) has published for the first time a complex diagram of mammalian brains.

Accordingly, the research team analyzed and scanned about 1,700 mouse brains and used 469 of them to include in the official report.

In the image, the glowing green is the transmission line originating from a region of the brain that plays the role of sensory translation, mostly tactile.

This diagram fully illustrates the link between about 71 million neuronal cells in mice. Scientists injected into a region of the brain of living mice a green virus and contained fluorescence. This virus will quickly infect nerve cells near the site of injection and after 3 weeks, they spread throughout the brain.

3D images illustrate the connection between 4 visual areas in the brain (green, yellow, red and orange).This region is closely connected, with other locations in the brain involved in visual activity such as the thalamus (pink) and the middle brain (purple).

Then, the mouse's brain will be taken out and scanned again in different ways, to generate about one terabyte of data for each mouse. By studying the path of the virus and processing images captured on a small scale, the team can create images that illustrate how connections between regions in the brain.

This is an illustration of the data being transmitted between different parts of the brain

The links between 215 regions of the brain are represented in a circular wiring diagram

After establishing the association of this specific brain region with other regions, a similar cycle is repeated in another position until the complete map of the brain is completed.
