The human brain is capable of creating structures in up to
11 dimensions, according to scientists. According to a study published in
Frontiers in Computational Neuroscience, the Human brain can deal and create in
up to 11 dimensions.
According to the Blue Brain Project, the dimensions are not
interpreted in the traditional sense of a dimension, which most of us
understand. Scientists found exciting new facts about the intricacy of the
human brain as part of the Blue Brain Project.
Neuroscientist Henry Markram, director of Blue Brain
Project and professor at the EPFL in Lausanne, Switzerland, said: “We found a
world that we had never imagined. There are tens of millions of these objects,
even in a speck of the brain, up through seven dimensions. In some networks, we
even found structures with up to eleven dimensions.”
Traditional mathematical viewpoints were found to be
inapplicable and unproductive once researchers studied the human brain.
The graphic tries to depict something
that can’t be seen – a multi-dimensional cosmos of structures and places. A
computerised replica of a section of the neocortex, the brain’s most evolved
portion, may be found on the left. On the right, several forms of various sizes
and geometries are used to illustrate constructions with dimensions ranging
from one to seven and beyond. The central “black-hole” represents a collection
of multi-dimensional voids or cavities. In a new paper published in Frontiers
in Computational Neuroscience, researchers from the Blue Brain Project claim
that groupings of neurons coupled into such holes provide the necessary link
between brain structure and function. Blue Brain Project is the source of this
“The mathematics usually applied to study networks cannot
detect the high-dimensional structures and spaces that we now see clearly,”
Instead, scientists opted to investigate algebraic
topology. Algebraic topology is a branch of mathematics that studies topological
spaces using techniques from abstract algebra. In applying this approach in
their latest work, scientists from the Blue Brain Project were joined by
mathematicians Kathryn Hess from EPFL and Ran Levi from Aberdeen University.
Professor Hess explained: “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.”
The researchers observed that brain structures are formed
when a collection of neurons – cells in the brain that carry impulses – form a
clique. Each neuron in the group is connected to every other neuron in the
group in a unique way, resulting in the formation of a new entity. The ‘dimension’
of an item increases as the number of neurons in a clique increases.
The scientists used algebraic topography to model the
architecture within a virtual brain they developed with the help of computers.
They subsequently confirmed their findings by doing experiments on genuine
brain tissue. The researchers discovered that by adding inputs to the virtual
brain, cliques of increasingly HIGHER dimensions formed. In addition,
investigators detected voids between the cliques.
Ran Levi from Aberdeen University said: “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.
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.”
The new information on the human brain provides previously
unseen insights into how the brain processes information. Scientists have said,
however, that it is still unclear how the cliques and cavities arise in such a
The new research could someday help scientists solve one of
neuroscience’s greatest mysteries: where does the brain ‘store’ memories.
