Scientists: The Human Brain Has Odd Similarities to the Entire Universe

A neurosurgeon and an astrophysicist entered a space.

The architecture of the visible universe, according to a group of Italian scientists, are astonishingly comparable to the neural networks of the human brain. While this may seem like the beginning of a terrible joke, it is a really galactic brain perspective.

Franco Vazza, an astronomer at the University of Bologna, and Alberto Feletti, a neurosurgeon at the University of Verona, recently found surprising parallels between the intricate network of neurons in the human brain and the cosmic network of galaxies. Their findings were published in the journal Frontiers in Physics. The scientists found that the intricacy and self-organization of the human brain and the structure of the cosmic web are comparable despite being approximately 27 orders of magnitude apart in scale.

The observable universe is made up of at least 100 billion galaxies that are loosely connected to form a web, whereas the brain is thought to have 69 billion neurons. Only around 30% of the universe's overall mass and the brain's total mass are made up of real galaxies and neurons, respectively. Additionally, galaxies and neurons both organize themselves on long filaments or strings like beads.

Dark energy makes up the remaining 70% of the mass in galaxies. The pair cited water as the human brain's counterpart.

Vazza stated in a statement on the research that "we determined the spectral density of both systems." This method is frequently used in cosmology to examine the geographic distribution of galaxies.

He continued, "Our analysis revealed that the distribution of the fluctuation within the cerebellum neuronal network on a scale from 1 micrometer to 0.1 millimeter follows the same progression of the distribution of matter in the cosmic web," but obviously on a larger scale that goes from 5 million to 500 million light-years.

There was an uncanny similarity in the clustering and the amount of connections coming from each node.

In the statement, Feletti added that "structural factors have once again discovered unanticipated agreement levels." Despite the evident and stark contrast between the physical forces governing galaxies and neurons, it is likely that the connection within the two networks evolves in accordance with comparable fundamental principles.

In order to help researchers better grasp how these structures have changed throughout time, the team is hopeful that their early findings may inspire new analysis methods in both cosmology and neurosurgery.
