Of their paper printed in Frontiers of Physics, Franco Vazza (astrophysicist on the College of Bologna) and Alberto Feletti (neurosurgeon on the College of Verona) investigated the similarities between two of essentially the most difficult and complicated methods in nature: the cosmic community of galaxies and the community of neuronal cells within the human mind.
Regardless of the substantial distinction in scale between the 2 networks (greater than 27 orders of magnitude), their quantitative evaluation, which sits on the crossroads of cosmology and neurosurgery, means that numerous bodily processes can construct constructions characterised by comparable ranges of complexity and self-organization.
The human mind features due to its vast neuronal community that’s deemed to comprise roughly 69 billion neurons. However, the observable universe can rely upon a cosmic internet of at the very least 100 billion galaxies.
Inside each methods, solely 30% of their lots are composed of galaxies and neurons. Inside each methods, galaxies and neurons organize themselves in lengthy filaments or nodes between the filaments.
Lastly, inside each methods, 70% of the distribution of mass or power consists of parts taking part in an apparently passive position: water within the mind and darkish power within the observable Universe.
Ranging from the shared options of the 2 methods, researchers in contrast a simulation of the community of galaxies to sections of the cerebral cortex and the cerebellum. The objective was to watch how matter fluctuations scatter over such numerous scales.
“We calculated the spectral density of each methods. This can be a method typically employed in cosmology for learning the spatial distribution of galaxies”, explains Franco Vazza. “Our evaluation confirmed that the distribution of the fluctuation throughout the cerebellum neuronal community on a scale from 1 micrometer to 0.1 millimeters follows the identical development of the distribution of matter within the cosmic internet however, after all, on a bigger scale that goes from 5 million to 500 million light-years”.
The 2 researchers additionally calculated some parameters characterizing each the neuronal community and the cosmic internet: the typical variety of connections in every node and the tendency of clustering a number of connections in related central nodes throughout the community.
As soon as once more, structural parameters have recognized surprising settlement ranges. Most likely, the connectivity throughout the two networks evolves following comparable bodily ideas, regardless of the putting and apparent distinction between the bodily powers regulating galaxies and neurons. These two advanced networks present extra similarities than these shared between the cosmic internet and a galaxy or a neuronal community and the within of a neuronal physique”.

The encouraging outcomes of this pilot examine are prompting the researchers to assume that new and efficient evaluation methods in each fields, cosmology, and neurosurgery, will enable for a greater understanding of the routed dynamics underlying the temporal evolution of those two methods.
