Scientists have found the Human brain can create structures in up to 11 dimensions. These dimensions, however, are not seen in a classical sense.
The dimensions are not understood as the classic definition of a dimension, which most of us understand, the Blue Brain Project explains.
A study by the Blue Brain Project discovered fascinating new details about the human brain’s complexity.
“We found a world that we had never imagined,” explained neuroscientist Henry Markram, director of the Blue Brain Project and professor at the EPFL in Lausanne, Switzerland.
A universe of multidimensional structures inside the brain
“There are tens of millions of these objects, even in a speck of the brain, up through seven dimensions. We even found structures with up to eleven dimensions in some networks,” Markram added.
By studying the human brain, researchers discovered that traditional mathematical views were not applicable and ineffective.
“The mathematics usually applied to study networks cannot detect the high-dimensional structures and spaces that we now see clearly,” Markram revealed.
Instead, scientists decided to give algebraic topology ago.
Algebraic topology is a branch of mathematics that uses tools from abstract algebra to study topological spaces.
“Algebraic topology is like a telescope and microscope at the same time. It can zoom into networks to find hidden structures – the trees in the forest – and see the empty spaces – the clearings – all at the same time,” explained professor Hess.
The Human Brain can create structures in up to 11 dimensions
Scientists discovered that brain structures are created when a group of neurons – cells that transmit signals in the brain – form something referred to as a clique.
Each neuron is connected to every other neuron in the group uniquely, creating a new object. The more neurons there are in a clique, the higher the ‘dimension’ of the object.
Algebraic topography allowed the scientists to model the structures within a virtual brain, created with computers’ help. They then carried out experiments on real brain tissue to verify their results.
The researchers found that cliques of progressively HIGHER dimensions assembled by adding stimuli into the virtual brain. Furthermore, in between the cliques, scientists discovered cavities.
“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,” explained Levi.
“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 sandcastle that materializes out of the sand and then disintegrates,” he added.
The new data about the human brain offers unprecedented insight into how the human brain processes information.
However, scientists have stated that it remains unclear how the cliques and cavities form in their highly specific ways.
The new study may eventually help scientists uncover one of the greatest mysteries of neuroscience: where does the brain ‘store’ its memories.
“They may be ‘hiding’ in high-dimensional cavities,” Markram concluded.
