By creating digital brains with an \u201cunprecedented\u201d level of biological information, the scientists aim to advance our understanding of the incredibly intricate human brain, which has about <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/19226510\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>86 billion neurons<\/strong><\/a>.<\/p>\n<p class=\"p1\">To get a clearer vision of how such an immense network operates to form our thoughts and actions, the scientists employed supercomputers and a peculi<span class=\"sumo_twilighter_highlighted twilighter-4243c6ee\">ar branch of math. The team based its current research on the digital model of the neocortex that it finished in<span class=\"sumo_twilighter_shares\">1<\/span><\/span> 2015. They probed the way this digital neocortex responded by using the mathematical system of\u00a0<strong><em>algebraic topology. <\/em><\/strong>It allowed them<em>\u00a0<\/em>to determine that our brain constantly creates very intricate multi-dimensional geometrical shapes and spaces that look like &#8220;sandcastles&#8221;.<\/p>\n<p class=\"p1\">Without using algebraic topology, a branch<span class=\"s2\">\u00a0of mathematics that describes systems with any number of dimensions,\u00a0<\/span>visualizing the multi-dimensional network was impossible.<\/p>\n<p>Utilizing the novel mathematical approach, researchers were able to see the high degree of organization in what previously seemed like &#8220;chaotic&#8221; patterns of neurons.<\/p>\n<blockquote><p>&#8220;Algebraic topology is like a telescope and microscope at the same time.

A large number of neurons would add more dimensions, which in some cases went up to 11. The structures would organize around a high-dimensional hole the researchers called a\u00a0<strong>\u201ccavity\u201d.<\/strong>\u00a0After the brain processed the information, the clique and cavity vanished.<\/p>\n<p class=\"p1\">The researcher\u00a0<span class=\"s4\"><a href=\"http:\/\/loop.frontiersin.org\/people\/108693\/overview\" target=\"_blank\" rel=\"noopener noreferrer\">Ran Levi<\/a>\u00a0detailed how this process is working:<\/span><\/p>\n<blockquote>\n<p class=\"p7\"><span class=\"s3\">&#8220;The appearance of high-dimensional cavities when the brain is processing information means that the neurons in the network react to stimuli in an extremely organized manner.\u00a0<\/span>It is as if the brain reacts to a stimulus by building then razing a tower of multi-dimensional blocks, starting with rods (1D), then planks (2D), then cubes (3D), and then more complex geometries with 4D, 5D, etc. The progression of activity through the brain resembles a multi-dimensional <strong>sandcastle<\/strong> that materializes out of the sand and then disintegrates.&#8221;<\/p>\n<\/blockquote>\n<p class=\"p6\">The significance of the discovery lies in allowing us greater understanding into &#8220;one of the fundamental mysteries of neuroscience &#8211; the link between the structure of the brain and how it processes information,\u201d elaborated Kathryn Hess in an <a href=\"http:\/\/www.newsweek.com\/brain-structure-hidden-architecture-multiverse-dimensions-how-brain-works-624300\" target=\"_blank\" rel=\"noopener noreferrer\">interview with <em>Newsweek.<\/em><\/a><em>\u00a0<\/em><\/p>\n<p class=\"p6\">The scientists look to use algebraic topography to study the role of &#8220;<strong>plasticity<\/strong>&#8221; which is the process of strengthening and weakening of neural connections when stimulated &#8211; a key component in how our brains learn.
