A new study recently looked at the differences and similarities between two of the most multifaceted systems in existence. Although on a completely different scale: the cosmos and its galaxies versus the human brain and its neuronal cells.
In particular, the study authors found that while the indicator is evidently different, the structure is unusually similar.
Under certain circumstances, the two systems appeared more similar to each other than they were to the parts of which they are composed.
Furthermore, the study proposed that vastly different physical processes can lead to very similar complex and systematized structures.

According to a recent study, the human brain works thanks to its network of nearly 70 million neurons that together make it up. ‘The universe, on the other hand, is believed to have at least 100 billion galaxies.
Comparison between networks
As described in the study, for example, the human brain functions thanks to its network of nearly “70 million neurons that together make it up”. The universe, on the other hand, is believed to have at least 100 billion galaxies.
In each of the systems, these are formed together in a complex network or network, distributed in strands and nodes, connecting them.
The aforementioned diffusion nodes are common to images of the universe and the human brain and explain some of the superficial similarities in the images.
However, in any system, those threads are made up of only 30 percent of the mass. Also, in each, about 70 percent of the mass is actually made up of parts that appear to be inactive. Such parts include the water of the brain and the dark energy of the universe.
“Spectral density”
To investigate the aforementioned similarities, scientists compared the way galactic works form within sections of the brain. They tried to better understand how the issue was spread between the two extremely different networks.
According to University of Bologna astrophysicist Franco Vazza, they calculated the spectral density of both systems, a technique frequently used in cosmology to examine the spatial distribution of galaxies. Vazza also worked on this project with Alberto Feletti, a neurosurgeon at the University of Verona.
Vazza also stated that their evaluation showed that “the distribution of fluctuation within the neuronal network of the cerebellum on a scale of one micrometer to 0.1 millimeter” is following a similar development of the distribution of matter in the cosmic network although obviously, on a larger caliber going between five million and 500 million light years.
The study researchers also looked at the ways in which networks of galaxies and neutrons connect, once again, discovering similarities with systems that appear to be more similar to each other than their component parts. To get a result, the researchers compared the average number of links between each of the nodes, as well as their way of grouping.
Unexpected levels of agreement identified
“Once again, the structural parameters,” Feletti explained, revealed unexpected levels of agreement. Probably, he continued, the link within the two networks develops following the same physical principles, despite the notable and evident difference between the physical powers that control galaxies and neurons.
The aforementioned two complex networks, Feletti said, show more similarities than those shared between a galaxy and the cosmic network, or a neuronal network, as well as the inner part of the neuronal body.
A paper describing the findings, titled “The Quantitative Comparison of the Neuronal Network and the Cosmic Network,” was presented in the journal Frontiers of Physics.
