A new study has looked at the differences and similarities between the universe, one of the most complex systems that exist at completely different scales, and the galaxies in it, the brain and nerve cells it contains. Researchers; They noted that although there are differences in the systems that govern these two networks, the universe and the brain as a whole have evolved with the same physical principles.
The researchers found that although the universe and the human brain are markedly different in terms of size, their structures show remarkable similarities.
In some cases, the two systems were found to be more similar than their constituent parts.
The study points out that quite different physical processes can create very similar complex and ordered structures. For example, the human brain functions thanks to the network of approximately 70 billion nerve cells. The universe is estimated to be made up of at least 100 billion galaxies.
These are collected in complex networks or networks in each system, distributed in long strands and connected by knuckles.
These scattered knots, familiar from photographs of the universe and the brain, also visually form some superficial similarities.
On the other hand, these connections in both systems only account for 30 percent of the mass. Passive-looking parts of the brain, such as water and dark energy in the universe, make up about 70% of the mass in both systems.
The researchers compared how these galactic webs form with brain regions to further examine the similarities. In their analysis, they tried to understand the distribution of matter in these two quite different systems.
The astrophysicist Franco Vazza, a member of the University of Bologna, who conducted the study with the neurosurgeon Alberto Feletti of the University of Verona “,We calculated the spectral densities of the two systems. This is a technique often used in cosmology to study the spatial distribution of galaxies. She said.
Our study showed that the distribution of fluctuations in the neural network of the cerebellum, on a scale between 1 micrometer and 0.1 millimeter, follows the same progress as the distribution of matter in the network in the universe. Obviously the scale in the universe is much larger, ranging from 5 million light years to 500 million light years.
Furthermore, the researchers, who also examined the shapes of the bonds between neural networks and galaxies and found remarkable similarities, found that both systems are more alike than the parts that make up their own essences.
The study compared the average number of connections between each node and the clustering patterns.
Alberto Feletti, “The structural parameters turned out to be unexpectedly similar here too. Despite the visible difference between galaxies and the physical forces that regulate nerve cells, the connectivity between the two networks evolves following the same physical principles.” She said.
These two complex networks (neural networks and galaxies) , the web in the universe and in a galaxy or nerve cell with a neural network more like that between.
