The human brain is a three-dimensional physical structure, but its network of neurons can be described using mathematical spaces with far more dimensions.

A famous study from the Blue Brain Project used algebraic topology to analyze how groups of interconnected neurons form complex structures called cliques and higher-dimensional simplicial complexes. In computer models of brain networks, researchers found structures reaching as high as 11 mathematical dimensions.

This does not mean the brain contains hidden physical dimensions or that neurons literally exist in an 11-dimensional universe. The “dimensions” describe relationships and connectivity within the network—patterns that are difficult to visualize in ordinary three-dimensional space.

Similar mathematical approaches are still being used in modern neuroscience to study brain connectivity, neural representations and higher-order interactions.

The remarkable part is that the brain’s complexity may be better understood not just by mapping where neurons are, but by studying the mathematical structure of how billions of them connect and interact.
