Despite tremendous technological advancements in recent years, there is still much about the human brain that scientists do not fully understand. One surprising recent study published in Frontiers in Computational Neuroscience has shed new light onto just how complex the brain actually is, with research showing that some of the structures in this vital organ have as many as 11 different dimensions. Studying these structures could give us an understanding of precisely how memories are formed.
The director of the Blue Brain Project in Switzerland, neuroscientist Henry Markram, said that tens of millions of these objects exist in each tiny speck of the brain, with many having seven or even 11 dimensions. He marveled: “We found a world that we had never imagined.”
While these objects only exist in three dimensions in our world, the mathematics that are used to describe them have several additional dimensions. The team used algebraic topology in a new way to uncover a whole world of geometrical structures and spaces with multiple dimensions.
These structures are formed when groups of neurons form what they’ve termed a clique, with each neuron connecting to all of the others in the group in just the right way to produce a geometric object. Cliques with more neurons create geometric objects with more dimensions.
