![]() There still is one enormous difference despite all these possibly unsettling mirror images. While the proportions might not always be exact, they are still somewhat scary. By studying the spectral density, or how power in a signal as opposed to its frequency, Vazza and Feletti found out that fluctuations in the cosmic web are on the same scale as those distributed within the network of neurons in the cerebellum, which mostly powers voluntary movements, balance, coordination and posture. 70 percent of the brain is water while the same percentage of interstellar stuff is dark energy. ![]() In the observable universe, there are at least 100 billion galaxies. ![]() There is a network of about 69 billion neurons in your brain. Many of these objects became their own star systems, and groups of star systems formed entire galaxies. It started at the molecular level when the Big Bang went off like a firework out of nowhere, and those molecules created larger molecules that kept accumulating and eventually became stars, planets, asteroids, comets, and other objects born from swirling discs of gas and dust. So is everything in the universe (at least what we can see of it). Everything in our brains is interconnected, from the molecular level to networks of neurons and other cells that create even more complicated structures. The human brain and the structure of the universe are two of the most complex systems in nature. “Despite the obvious differences in their internal interactions, complex networks do tend to evolve according to similar laws, in order to economize on energy and fill space in a more efficient way-but that’s just the start of the quest.” “Our research tries to show that with shared statistical tools, both networks can be analyzed in a quantitative way, and we found a good degree of structural similarity across a broad range of scales,” Vazza told SYFY WIRE. This study and the work it inspires in the future could revolutionize both cosmology and neurosurgery. Unlikely as it seems, astrophysicist Franco Vazza and neurosurgeon Alberto Feletti, who recently published a study in Frontiers in Physics, have merged their knowledge of the brain and the cosmos into something with the potential to advance both sciences further than they have ever gone. Neurons form in long filaments or nodes between filaments, just like galaxies, and there is mass or energy that has seemingly passive role in both-water in the brain versus dark energy in the void of space. Besides being two of the most complex systems in nature, the number of neurons in your brain is eerily close to the number of galaxies in the observable universe. ![]() This is what you get when you put the minds of an astrophysicist and a neurosurgeon together. The network of neurons in the brain and network of galaxies in the cosmos might actually be reflections of each other. There is a whole universe in your brain, but did you ever think that your brain could be a reflection of the vast universe out there? ![]()
